I am looking at upgrading my dual GTX285 setup and have been looking at maybe going over to ATI and putting in a 6950 card with the look at then putting another one in at a later date. What do you guys think of this upgrade? will one 6950 be enough to replace my 2 285s? all though the DX11 compatability will be welcome.
Ive been trawling through all the charts etc and I am not too sure, pros and cons to all this? noise temp performance etc...
Im currently running an i7 at 4gig with 6gig mem and SSD hdd and play all my games at 1920 x 1200.
From the benchmarks I'm seeing, 1 6950 (reference) has about 10-15% less performance than 2 GTX 285's (reference) in SLi.
1 card will definitely use a lot less juice, produce less heat, you wouldn't have multi-gpu scaling issues or any SLi issues because you'd have one GPU, however you'd get "slightly" less performance. However, 2 6950's in crossfire would destroy 2 GTX 285's, so if you do plan on adding another 6950, I would say that it's a pretty good idea. Just make sure you have enough juice to power the 6950's (I'm sure you do, running 2 285's takes quite a bit in and of itself).
Not to mention, as you stated, DX11 compatibility would be a an added perk.
