I know that if I pick the Asus I should get the v2. Only thing that has my worrying is the weight of the cooler? Will that be a problem (I don't move my case very often)?

You will be fine. If you are really worried about it, You can always get a power jack.

its hard to say. If the 6870's are at stock speeds then the single 7950 @ 1100mhz will beat the 6870's.

For reference my 7950@ 1100core scores P9054 in 3dmark11. The 3gb frame buffer vs the 1gb frame buffer is what really hurts the 6870's they have the gpu power but are limited by memory in most modern games. @ 1080p though 1gb frame buffer usually works out ok.

Yes, you will see the world of difference.. The benchmarks are about the same compared to a stock 7950.

I went from 2x 6850's clocked at 920MHz Core and 1100MHz on the Memory to a single 7950 which is now clocked at 1100MHz with 1250MHz on the Memory.
Best thing I've ever done, more fluent FPS in BF3 and such. Less power and less heat problems too, no driver issues also! The 6870 + 6850 had the worst driver issues I've seen in a while.

I'd do it, the 3GB framebuffer is worth it alone. I can play skyrim now! It was completely dead for my 6850's EVEN if I disabled crossfire. rolleyes.gif

Sell those 6870's for $120+ each and you'll have a nice upgrade for as little as $60. Yes it's an upgrade.. Trust me.

EDIT: I didn't really benchmark it so to speak but any game just feels so much smoother and more fluent with it's FPS. Even some games where I got more (BF3 at times) the lowest FPS count and average are a lot higher as I've got a single graphics card to render it all and there are no driver/CFX issues.

I went from a 5970@890/1200 and a 5870@940/1200 and my 7970 feels faster and smoother by far even get more fps in some stuff then i did with my old trifire not to mention runs so much cooler.

clock for clock HD 7950 is 3 - 5% slower than HD 7970. HD 7950(1.1 Ghz) matches HD 7970 Ghz (1.05 Ghz) and is easily faster than HD 6870 CF.

http://www.techpowerup.com/reviews/AMD/Catalyst_12.11_Performance/23.html

1920 x 1200

HD 6870 - 56
HD 7970 Ghz (12.11 ) - 117

HD 6870 CF is in the best cases 1.8x HD 6870 perf. In DX11 games like BF3, Crysis 2 the HD 7950 (1.1 Ghz) is 2.25 - 2.5x times HD 6870 perf. Also the single HD 7950 will provide a much more smoother and consistent experience without multi GPU issues like micro stuttering. In games where CF does not work well the gap will be even more. Its a significant upgrade.

Hey guys. This is a question for those who had both experience with 680s and 7970s. Is it true that the 12.11 drivers make the 7970s and 680s equal in BF3? I'd like to hear from actual experience, not from website reviews, etc. thanks! smile.gif
