4890 CFX vs 6950 1Gb

post #1 of 19
Thread Starter 
Alright, so this weekend i am going to pick up the Sapphire 6950 1GB from MicroCenter. Im going with the 1Gb Version for lack of a large amount of money, plus i only run at 1680x1050 and at most will go to 1920x1080/1200, and from my understanding 1Gb is plenty for these resolutions. So how much of a performance increase do you think i will get, besides the benifits of a single card over crossfire.

Hes upgrading to a 6950, not 6850.

I upgraded from a single Vapor-X 4890 to a Sapphire 2GB 6950(unlocked shaders) and wasn't impressed. Although I didn't see a big difference, in beches the 6950 kills a single 4890.

Check this thread.

ment to say 6950 (thus the unlock)
and going from dual 4890's to one 6950 would not be a huge upgrade, unless he is unlocking or planing to crossfire

very little, not worth it, imo.

I went from a 4870x2 to a 6950 2gb. It was a bit smoother since it's one card but the frames rate jumped very little.

Your 4890s would be a bit faster than my 4870x2 was, too.

You will need a 580 or two 6950s for it to feel like a serious upgrade. One 6950 will use waay less power than 4890s, though.

1gb version of 6950 is not unlockable
4890 xfire is already enough for you
unless you want some space in your case and want dx11 (which is worth) you should go for 6950
and 6950 is not a huge improvement over 4890x2

I'm pretty sure 4890 Crossfire is faster than a 6950.
post #9 of 19
i went from dual 4890's to a GTX480 and now a GTX580. in terms of raw performance the gtx 480 will be the same as the 4890's, but gameplay will indeed be smoother. and for the games that do not support crossfire they will be a massive jump in frame rates.

in the end i think the 6950 is a suitable upgrade, if not the best.

OP, what's your motivation to replace your 4890's? I think in games that don't support CFX, you'll see a noticeable difference, but for other games, it will probably not be all that noticeable.

Save for maybe Crysis 1, are you unable to run games at 60fps at 16x10 with your CF 4890's?
