Sapphire 6870's Cross Fired and Overclocked

OK so I just bought two new Sapphire 6870 Vapor-X video cards and they are sweet!



Strangely the two identical cards came with different factory installed BIOS revisions. One card had been flashed to run at 930/1150 and the other was at default of 900/1050. So I flashed both of them to the TOXIC BIOS of 970/1150 with ATIWinFlash.



Fans are not too loud even when turned up and temps look great (these are idle temps, but load temps were about 70C)!



So I went ahead and ran 3D Mark Vantage to see how they run.... These are running on the system in my signature.



and just for comparison, a 3DMV run on the same settings with a pair of Vapor-X 4890's



A 54% increase in GPU performance (as expected)!

3DMark11 (Performance): P8772 3DMarks <-----Not sure if this is all that good or not compared to most scores... havent seen a chart/distribution yet

My 6970 at 975/1450mhz get's 24500 on 3d Mark Vantage and 5900+ on 3d Mark 11. 6870 Crossfire is a really powerful affordable setup. You could have gotten the 6870x2 though, was this cheaper?

Oh heck ya!

The cheapest one i could find was Powercolor 6870X2 on Newegg is $477.86 after shipping with a $30 rebate.

My Sapphire 6870 Vapor-X's were $199.99 each with free shipping and $20 rebate each..... This one is a no-brainer

Yep. I like my Asus 6870's.
What was your oc on the cpu?
