Don't bother with 2x GTX275. Get 2x HD5830 or 2x HD5770. The HD5830 crossfire will use much less power, and it'll be much more powerful (maybe not much more, but it'll be better).

 

[adwbeck]

are there enough extensions from that particular psu to do it?

 

[shadow187]

No, you need two more 6-pin PCI-E connections.

Yeah, if you are going to be spending a large amount of money on a video card(or cards) right now you will want DX11. If you are set on Nvidia preorder one of the GTX 480s while you can get in on it early.

yeah ive decided to go with 2x 470 cards when they come out in 2 weeks

What is your resolution? Is there a reason you are set on using 2 cards?

 

[obsidian86]

you goona need least 950 watts for 2 470's

 

[adwbeck]

my resolution is 1920x1080, just want to run 2 cards for the hell of it

Assuming your PSU has two rails, one of them MUST be over 32A.
