So I was thinking getting me another HD4870X2 and run both in crossfire on a Gigabyte GA-P35-DS4 motherboard.
Currently I've got a Corsair 750W PSU running with one HD4870X2.
Question is: Can I add another HD4870X2 without getting myself a more powerfull PSU?
current system specs:
[code]
-MOBO Gigabyte GA-P35-DS3 (will be exchanged for a GA-P35-DS4 if another gfx card comes in question)
-CPU Q8400 @ 2.66Ghz (default) with stock cooler
-PSU Corsair 750W
-GPU HD4870X2 (gainward golden sample)
-RAM 2x 2GB Corsair dominator 1066Mhz DDR2
-1x SATA2 HDD 500GB
-1x SATA HDD 300GB
-1x SATA DVD drive
-4x 120mm fans
-1x 200mm fan
[/code]
I don't think another 4870X2 would work. I've had one before and it maxed out at roughly 650Watts. I would upgrade to a good Quality 850W.
Actually, your CPU would probably bottleneck them.
And that would count as quad-fire, which really gives no performance increase.

This.
Also, 1 good card usually outdoes 2 lower spec cards.
So should I rather go for a new gfx card then?
Old Card, replace it with a new one that will most likely outperform your quadfire setup.
