I've been offered a Geforce GTX680 for $300. Obviously, for crunching it would be sub-par---and another $300 would be rough right after the last HD7950. But that's an amazing price for the card. I'm thinking I could probably get a straight trade for a HD7970 or add in a bit of cash for a pair of HD7870s. What do you guys think? Should I jump?

Jump, and then jump again. That seems like a solid deal on a 680, so even if you trade for a 7970, it's a nice deal... (imo)

I don't think finding a trade for a 7970 will be easy- unless maybe if you already had someone in mind and willing.

I mean I was tempted to buy that card, but compute performance would be a downgrade.

Hey guys, how many WU's a HD7850 can run at once? 10? 8? 6?

Still have some money left from my year end bonus, the wife is already happy so no need to buy her anything else So I guess, it's time to do GPU upgrade.

I can afford HD7870 but if single HD7850 can do 8 or 6 GPU WU's at once, the choice will be HD7850 + extra RAM or Intel 330 120GB SSD hohoho.

Any help, advice, and insight would be appreciated. Thanks.

7850- 4-6 wu's

7870- 6-8 wu's

 

[okidna]

7850- 4-6 wu's

7870- 6-8 wu's

So 6 is the maximum. I guess I'll go with HD7870 then.
Gotta need a "budget boost" (a.k.a. sell this 560Ti) if I still want extra RAM or SSD

Thanks Norton

Looks like my 9600gso and 5450 is too slow for BOINC...
Any tips for getting the stuff working? or do i just leave the GPU projects out

 

[brandonwh64]

Well guys sorry for being a ghost over the holidays but I am still here and trinkling in points from the GTS 450's in SLI but today I fired back up the 6950's to get back atleast in the top 20!

Guys, need some advice..
I need to know if it is possible to manage 4 WUs on a 7770 with the C2D E4500 (2.2GHz). I guess it would mean 0.5 Core/thread for a 0.25 GPU. If so, I shall get that(or 7850) for the time being.

Ideally, I am planning a mITX build with a lower TDP processor+GPU. I could get the GPU rightaway. I am unsure about the rest of the build since I am inclined to wait for Haswell because of its speculated overall efficiency & better IPC/FLOPs. So, if I there is a possibility I can manage multiple GPU WUs with the C2D for now I would get a HD7xxx gpu by next week and then get the parts for the rest of the build later.

Please let me know of your thoughts on this.. Thanks!

That C2D should run fine with a 7770 or 7850- the only thing you may need to do is step down to 3 gpu wu's on the 7770 rather than 4 but it shouldn't hold back the output too much.

If you can swing the 7850 then go for that one- It's a much better card than a 7770 for just about everything...

I never had a 7850 but two things I'm sure of - it does better in gaming/GPU crunching and it uses more energy. The 7770 will at stated in previous post by Norton run 4 GPU units even on a slow CPU.

There is only one person who can tell if 4 or 3 WU is better in your rig. Guess who I haven't seen the formula that takes all in to account - RAM speed (both speed and transfer rate), CPU speed, GPU speed, PC usage, disk speed, error rate and the ones I haven't looked at yet. I found that even on almost identical set-ups the output will vary. I got the same amount of points running two 7770 on a slow i7 920 (slow HD too) that I get from a much faster i7 970 AND the latter is 100 % dedicated to crunching.

Came up to work and found the P55 rig down. Reboot it and get code 85, which is supposedly a video problem. I have 3x GTX 460s in there so I'm going to have to hook it up to a monitor and diagnose it.

OH NO! this sucks man! I thought my 2600K at work had quit but the WU was so low that I wasn't showing up on the pie page. two GTS 450s only get like 10K WU

Yes, sad isn't it. I pulled mine and the rig is now in waiting position until it I need the heat. My GT 525M does a better job (almost).

Another 2yo laptop hard drive lost. Better than something else going, but I just used my last spare to get it running again.

I have some spares if you need!

Indeed, just do not select the "give me GPU work" option in your WCG account. Note: "Help Conquer Cancer" can be selected because that project als has got CPU WUs available.

I've got my AMD X2 running again. I also have a new C2D setup that I'll be getting online soon enough. I just need to get some more DDR2 RAM to get them up-to-spec.

You and your Core 2 Duos

Hey, they're dirt cheap and do a decent job. Not as well as the AMD GPUs, but whatever, I do value my CPUs to. And I still have my half-dozen Core 2 Celerons at school to fire up again Saturday

I know, it's just interesting to see someone acquire an army of them.

 

[Peter1986C]

Core 2 Duos are good general-purpose CPUs.

 

[Nordic]

Speaking of core 2 duos... I got a 1.86 ghz core 2 duo with a biostar matx board for dirt cheap awhile back. Meant to make it into some sort of file server but don't exactly have much of a need for that. I know it can overclock quite well. I only pushed it to 2.3 ghz myself but the previous owner said he had it up past 3 ghz with just better than stock cooling. Maybe I should make it into a WCG rig or something.

 

[Jstn7477]

Yeah, I use my X6800 for my home dedicated server (runs Minecraft and other stuff) and does it pretty well. Good 775 boards are hard to find anymore and usually you have to wait for people on tech forums to put them up for sale, but I have no interest in buying any more of them.

 

[Peter1986C]

Getting good motherboards for them is a bit tricky indeed.

Darn, miss my old 775 systems.. sold my p5q deluxe with a q9450, and another system with my e8400... good memories....
