Nice overclock, but was hopeful to reach higher tbh. Seems its volts and not temps are what are holding this card back. Now that I have watercooled my rig though, I will never be going back to air!

Same here. Once you go water especially for the GPU i cant stand air. I just find water cooling HOT GPUs like HD 6990 a bit more rewarding. For me HD 8990 will be my next card.

Also fyi, xfire HD5850s are not as good as a HD7970. Both heavily overclocked.
HD7970 is on par/better than HD6950s xfire. Both heavily overclocked.
How do I know? I have had xfire 5850s,5870s,6950s. Proof?
Check my benchmarks a few pages back.
You actually sound mad like you have to prove that you didn't make a stupid purchase on the 7970 lol.

Anyway, Newbie2009 was kind enough to get my some of his 7970 Crysis 2 benchmarks. Now the 5870 might seem more powerful in raw gpu power, but I needed a test that featured new technology to show the downside of have 2 card from 2 generations in past.
7970 OC Benchmark results: 91fps no AA, 88FPS x4AA
643
5870 OC Crossfire: 85FPS no AA, 38FPS x4 AA

Tesselation didn't seem to be the downfall of crossfire 5870's are for the most part, the FPS was competitive with the HD 7970. Adding AAx4 to the mix had the 5870's fall flat on their face as vram was maxed out, a huge difference in performance from the 5870's to the 7970. This makes me wonder hd 2gb variant of the 5870 would work on a benchmark like this.

I don't mean to necrobump, but I wanted to reference this post you made. The reason the 5870's fell flat on their face when 4xAA was enabled, wasn't because they ran out of VRAM. It is a driver/software compatibility problem with 58xx cards and Crysis 2, using AA. I have 2x 2GB 5870's, and turning on 2xAA slices my framerates by 50%, and causes my GPU usage on both cards to run under 60% each. It's a definite driver or software bug with Crysis 2 and these cards.
