I'm going to slowly upgrade (read: rebuild) my computer and I'm trying to figure out what GPU setup will work best within my budget. I'm fine with the performance as of right now for work, but I'm trying to get a little more for gaming.
Games I play are generally Civ V, Cities XL 2011, Skyrim when it comes out (tons) and maybe Battlefield 3. Wouldn't mind trying out Starcraft 2 on of these years. Oh, and I swear I'll get through Mass Effect 1 & 2 this coming year.
Anyway, I'm running a AMD Phenom II X4 965BE with 8gb ddr3 and a HD 5770 @ 1920x1080 resolution.
My options look to be:
1. Buy a HD 6950 w/ 2gb ram
2. Buy a HD 6870 w/1gb ram now and then buy a 2nd one in say 2-3 months (depending on holiday deals).
3. Buy a new Mobo and a 2nd HD 5770.
Trying to stay away from Nvida because I also have a 3D projector I hook the computer up to from time to time. And I don't mind upgrading in say 2013, so don't need something that can account for every possible game upgrade for years.
Not sure what the projector has to do with nVidia / ATI since I run my 3D tv off my 560 Ti but anyhow.
I would go with the 6950, as it will be able to handle everything you need it for. SLI is not going to really help you with anything, and you need larger PSU and probably a different MB, so I would just go with the 6950.
If you were willing to reconsider the nVidia cards a 560Ti or 570 will be better performing and should be around the same price point.
