I wanted to add to my earlier reply
do you think i'll be okay with a 2x24GB DDR5 + RTX 5090 + 9800X3D setup for the long haul?
MY JOURNEY:
I want to share the procedure I did when building my PC as it may help you out. While somethings in this may seem overboard, I don't care, I'm investing a good amount of money into my build so I always take precautions. Keep in mind I am always looking at the failure end of things, the what if, or this could happen, I don't dwell on it, but I do keep it in mind. The way I see it is if there is a way set it up so certain failure wont happen, it doesn't interfere with the budget, or doesn't over complicating things, then why not just do it, which is what I did on my build (I'll explain this with my GPU and the CPU).
HOW OFTEN I WOULD BUILD MY PC:
I usually get a new PC every 5-6 years and I always have it built (Until now I've never built it myself so this is the very first time I put my own PC together. Knowing how all these components are and the way marketing works companies cause FOMO (On purpose or not, it's a part of marketing). I wanted to go way beyond that so I knew by building my PC to the point there would be nothing that could use the power of anything I have for at least another 7 years past the original 5-6 year mark. I know how games on PC are built which means understanding the main component around that is the GPU which revolves around the video RAM. This was going to be the most expensive part on my entire build. For me not falling into the FOMO trap is still some times difficult, but I have a way to refocus and not let myself get distracted which did happen a several times during this build.
WHAT I WANT MY BUILD TO DO:
My build is specifically for playing games, surfing the net, watching movies, and editing 4k 360 video. I set my build up to go with DDR5
GETTING LUCKY:
Anyone that says luck doesn't play any part in building is not in reality (The silicone lottery plays a major part in this) Anyway I got lucky with a lot of my components by either getting the one component out of all the others that didn't have certain problems others did (Such as the motherboard in this case) or avoiding the connector issue causing fires with the RTX 4090. I always get Corsair PSU and it turned out that Corsair just happened to make the single cord for the GPU to PSU connector so it was compatible. Furthermore at this time only the RTX series 30 and 40 GPUS had a setting in certain sites like youtube that would allow for watching videos better (And yes I think things like that are stupid). I also got lucky by finding out about the thermalgrizzly plate for the CPU and the anti sag support bracket for the GPU lian-li made. (I don't care how well the motherboard is designed to keep the weight of a GPU like an RTX 3090, I'd still rather have it supported to not put that type of stress on the plug in socket (This CPU and GPU bending is what I mean by setting up to avoid a problem (Sure it's unlikely, but I don't even want to chance it). The motherboard I got also already had the BIOS upgrade it needed for 13th Gen CPU. If not, because the motherboard doesn't have a way to flash it with a USB drive, I have to do it from the BIOS itself which meant having to use a 12 gen processor in order to update the BIOS to accept the 13 and 14th gen Processors (Now you can see what I mean by getting lucky). I'm a professional entertainer (I'm a magician) I won 10k on an internet talent show for a major Streamer and that's how I was able to purchase my RTX 3090ti. To this day I will tell anyone that anything over 1k for a GPU is idiotic and to avoid it even if you have the money (But that is just me) anyway I was originally going to get a 3080ti but couldn't find one so I said screw it, bit the bullet and got the RTX 3090ti but I had a problem finding that and I got lucky to get the last one in Stock at a Best Buy (I'll explain the reason for purchasing it at Best Buy below in pricing) I also happen to get my CPU and my Case there at the same time. The monitor I got I found brand new on EBAY for about $525 with tax and shipping. A final aspect to take into consideration is how long a component has been out for. The longer it's out, the less likely chance of a problem happening is case in point the Samsung 980 and 990 pro M.2NvME firmware problems. I was originally looking at those but after reading a firmware issue happened I just went with the Kingston one I have now (Again I'd rather avoid any possible problems)
PRICING:
When it comes to pricing another thing people don't think a lot of people think about is the price to power ratio, (there is no point in getting higher powered components, then gimping them with other lower end parts (I explain this situation below in the upgrade section) there are certain things I will only get from specific places due to the amount of money I'm investing so I do not mind paying slightly extra or the TAX for things like my GPU and CPU I bought at best buy. If something happened, I have an actual outlet I can walk right into and get anything I need answered right then and there instead of having to pay for shipping and crap..You get the idea. Anyway RGB is a major problem for several reasons (Some of which I will not get into). While I get the appeal, I absolutely cannot stand RGB mainly because it's just an excuse for companies to jack up the price, but now instead of just being an accessory of choice, it's being crammed into and onto every single PC part as part of it and it cannot function without it. It's crap like this that affects the pricing for people like me. I'm almost being forced to take RGB whether I want to or not, and I will have to pay a higher price for no reason for component that has something on it I have no desire to have. Saying just don't use it isn't the point and a weak argument not using it isn't the same as not having it on the part. (As I said I have other issues with RGB being on parts that I won't get into). So for me getting an entire PC with no RGB is possible, it was a serious chore to pull off. Anyway I always search around for parts and I managed to get my motherboard for $180 brand new At the time it was still around $225-$250. When it came to the Case, I was originally going to get an NZXT H9 flow but it was out of stock everywhere (And I do mean everywhere even on their own website) so I settled on an NZXT H7 Flow which saved me about $80 which ties into the upgrade for my CPU, I was originally going to get an i9 12900k but realize it would be smarter to just go with the i9 13900k because not only had it been out for a while, but was only about $90 more, so I took the extra $80 left over from the case and used it to buy the i9 13900k. I'm also getting an additional 32 GB of RAM so I'll have 64, I'm thinking about even more again I know it's serious overkill but this is just how I think.
WHY DDR5 AND NOT DDR4 SINCE DDR4 IS CHEAPER:
This is where everything comes together nicely. I look at the overall bigger picture. In my head, despite DDR4 is still strong, I see it far too often where people (And this is mainly gamers) MUST have things built now instead of taking a few months to save their money then trying to use the argument they don't have the money (Wring they do have the money they just don't have it NOW (Things aren't going to become obsolete in 6 months or even 2 years for gaming especially with all the components out now) way too many people talk getting DDR4 parts to save money, then when things upgrade, they wind up spending more money to get a higher DDR4 or DDR5. Which means they didn't save money, they wound up spending more which is what they complained about to begin with. Instead of buying DDR5, they went the cheap route and wound up spending more money in the end only to do what they should have done in the very beginning to which they argued they don't have that type of money when they do, it just seem that way because of how they spent it. Just save your money and upgrade to a higher amount (Again things for gaming aren't going to become obsolete in the next 3 years. The way I see it is this, eventually everything is going to be moved over to DDR5 (Yes it's still a ways off) but why wait, just make everything DDR5 now. Besides DDR5 can do and use everything DDR4 can do so why anyone not get the higher DDR and cover it and not have to worry about it. When it eventually all happens, I am already setup and ready to go. Besides the DDR5 ram I got is going to still be far more sufficient when things do turn over to DDR5. I also believe DDR5 will shoot back up in price once things start transferring over so now I'm using this time to save money by buying it cheaper before that change happens and companies once again jack up the price. I'm looking into putting more RAM into my computer which I already planned to do.
UPGRADE YOUR WHOLE PC AT ONCE IS FAR MORE BENEFICIAL:
When you upgrade one or two components, you wind up having a problem with the rest of your computer. The power of the new component gets gimped then you wind up having to upgrade another component which gets gimped, and before you know it you've upgraded your whole PC. Here is what happened to me, the first usable upgrade I got for my PC was my RTX 3090ti, putting this into my computer worked because I had an 850 watt PSU. But I already knew was I going to run into was be able to utilizing the entire power of my GPU since I had older components. My CPU and RAM was gimping my GPU. Since I was already rebuilding my computer anyway this didn't bother me as much because I knew eventually I would be able to utilize the entire power of everything. This is where I ran into an unforeseen issue which had to do with my monitor. While I had access to the full power of my entire system, it turned out my monitor wasn't up to par so I still wasn't getting at the full power so now I had to figure out how to upgrade my monitor for a cheaper price. So as you can see, this becomes a vicious cycle because when you upgrade you need to make sure you aren't just gaining access to the power to price ratio, you want to make sure that you are actually able to use what you're paying for. Having access and being able to actually use what you have access are not the same thing) again this is just how I think.

Again I want to point out that sure I may have put this amount of money into my PC it still took me almost 10 months to do and by the time I was done, nothing advanced to the point anything I have was made obsolete, it's now over a year later, and the 3090ti is still relevant/valid and still will be even after a year of the 50 series cards being out. BTW Until this build, I've never built a PC myself and I had a lot of help from a friend of mine and I was embarrassed and frustrated that it took me over 10 hours to put this thing together but apparently that's normal for first timers. He also helped me tweak it to safely be able to run my CPU at a decent speed.
Anyway, that's my story
I hope this really helps
