Check nVidia's site for compatibility. www.slizone.com

Well perhaps the use of a single card yes however for SLI im thinking you will need a stronger amperage. I could be wrong but perhaps look into an OCZ gamestream.

yea if it comes down to it not working, im not going to do it because i dont want to replace anything, i just want to add. Im happy with what i have, i just want to add more. But not replace because its still new...er

I mean at a scrape perhaps however i wouldnt want to risk it just incase it doesnt. one single Powerful card would serve you just aswel anyway mate.

it says teh NeoHE 500 w is compatible it has i beleive 3 12v rails at 17 a each. I think, im not sue how to read all those specs. but mine has 2, one at 17 and the other at 19. is that extra 17 a a huge difference?

Yes the Extra 17 can make a huge difference. I would say if you only have those 2 rails then NO i wouldnt risk SLI however if you have 3 rails i would say ur looking at a better chance in getting it

Ooo close call, I'm going to say yes it will handle it though as that powersupply should be honest with it's output
