A little background about my GPU collection. I bought a BFG GTX 9800GT 1GB Eco Edition (from a local shop) in 2009 for my WinXP machine, and it took awhile till I found another 9800GT card to run my first SLI machine. However (this is before online shopping was popular), big oversight, new to me, but you need equal Vram to make it work, and the second card I bought was identical BFG, but with 512MB of Vram. Apparently there was driver patch that would allow SLI, but I never tried. Hence, the second card remains unused sealed in the anti-static bag. The other card was never used but I did take it out of the anti-static bag to admire BFG's take on the GTX 9800GT. I thought it was the most beautifully engineered product of its day, hey, it was ECO friendly...,environmentally conscious...blah, blah, blah LOL.
Anyway, my Xp machine now is a Pentium4 Prescott (hyper-threading), 4GB of ram on an Asus motherboard, it sports a HIS X1950 PRO IceQ 3 Turbo 512MB AGP Rev.2 graphics card. Bit of a monster from its day, and you need a really good PSU to avoid the BSD. Unbelievable that this machine runs flawlessly to this day, it introduced me to my favorite games Doom and Wolfenstein at the time, and we can still browse YouTube.
The PNY GTX 550TI, was in my wife's work HP computer i7-2600S, I upgraded her machine to a Zotac GTX 650Ti 2GB edition. Originally, I upgraded her to a Zotac GTX 650Ti 1GB edition, but the cooling fan went south. I called Zotac tech support number and asked for help, and they agreed to send me a new cooling fan replacement that I installed; Zotac has great customer relations, at least in my experience. However, the wife needed her computer to be useful pronto, so I went out and bought the 2GB edition, it was the last one in stock at the time from Staples locally, the GTX 750ti was on the shelf but was a little pricey compared to the last 650ti on the shelf. On the table is the 1GB version. I keep all the original boxes. And she still uses the HP intel i7 2600S, (8GB ddr3 and SSD boot disk) for work, including video conferencing with Microsoft Teams, SKYPE with family and friends, MS Office productivity without a hitch.
More to come....
OK, the Crysis 2 GPU is an EVGA GTX 560ti 1GB version, picked this up a bout 5 years ago for $100, good price at the time. Didn't really need it, just wanted to have it as a backup in case my SLI GTX 660's gave up the ghost, and it looked cool.
Yes I finally built my SLI machine, with an ASUS P8Z77V-Deluxe, and i7-3770K, 32 GB Corsair Vengeance, 2 EVGA GeForce GTX660 SC 3GB editions in SLI (3gb was a lot in the day), 500GB boot disk and 2 1TB HDD for storage, and a Corsair 750W 80plus Gold modular PSU in a big Cooler Master chassis. This is my daily driver today, and I'm going to be perfectly honest, never had a BSD, or any stutters in gaming, and temps never exceeded 90C during benchmarking (TimeSpy, Heaven, CineBench etc) extreme settings in all at 1080p in Win7.
This rig stayed in SLI from 2012 to 2018, but when I upgraded the OS to Win10, I switched to an ASUS GTX 1070 Turbo edition that I found used for $300....I was keen on trying VR, as it was becoming the trending thing 3 or 4 years ago. The metal backplates that came stock with the GTX660 and (and the GTX1080) was a nice esthetic touch that exemplified EVGA's attention to detail in their products.
I picked up the EVGA 1080 SuperClocked edition a few months later for $400 as a backup, as I found thru my research, that the ASUS turbo edition may run hot because of its blower style. But in monitoring its temp I've never seen it exceed 80C under load. It keeps going, and the GTX1080 keeps waiting. Apparently its a good time to have a backup GPU of its caliber.
