4890 CFX vs 6950 1Gb - Page 2

post #11 of 19
My bad, I was comparing to 4870 x2, not 4890 x2.

Still, the upgrade is substantional - 6950 with much less power consumption, much cooler, better OC, more shader processors (new games are shader limited), higher Vram clocks, DX11.

It's not, comes close but not faster.

everything but the better oc would be relevant. both should clock to 9xx easily.

it's just 9xx on the cayman core would be more substantial than the 4890

Save for maybe Crysis 1, are you unable to run games at 60fps at 16x10 with your CF 4890's?
My motivation was that i wanted to go back to a single card. I mean i have no trouble with the drivers or anything, but i have been having the occasional power issue, and this should fix that. Plus some of my favorite games don't use crossfire well (GTA4, Fallout 3, and Crysis). Plus, i just think its time for an upgrade.... Plus I Like Dx11

I went from a single 4890 to a 6950 and saw an average of 65% increase across the board. No clue how 2x 4890's compare to 1 though. I have the link to my benchmark in my sig.

Coming from somebody went from 4890 CF to a GTX 570 and now GTX 570 SLI, I can tell you that the performance increase, in terms of sheer power, is not worth it. Your 4890's will be faster in just about everything save for games not supported for crossfire. However, if you can handle equal if not lesser performance for a little while and plan on getting another 6950 in the future, it will absolutely be worth it. My first 570 was barely faster than my 4890's. When I got my second, however, I was pushing out frame-rates roughly double what my 2 4890's did (570 SLI = a little more than 2x 4890 CF performance).

I think its worth it for A; Single card B; less power draw C; Less heat D; Direct X 11, blah.

Overall power on games that use crossfire well, not much noticeable difference. On games that do not use crossfire as well, obviously big performance increase. Also another plus is you can get another 6950 in the future.
