Crossfire 6970

[samtronswt]

Looking to crossfire my one 6970 2gb card!

Wondering if anything from my computer would hold back the performance.

OS: Windows 7 Professional 64 bit
Ram: 8192MB
Processor: AMD Phenom II X6 1100T Processor (6 CPUs), ~ 3.3GHz
DirectX: DirectX 11

Power Supply is currently a 650 Watt!

I know my motherboard has crossfire capability but would anything there be holding back the performance from the second card being crossfired?

Need to know what the mother board and the other vid card is.

I have a sapphire ati 6970, would be getting the same card and motherboard is: asus ms a99x evo.

It's cost effective way to almost double your performance when gaming. My AMD is at 4.1ghz with a hd7770 gpu and a 650psu and it should run crossfire with no problem from what I have read.

You overclocked? And so a 650 watt would be enough?

I read a test review on a pair of 7870's, they used about 490 watts peaked. I think a single card would be 20-25% less at minimum.
