Hello All,

So I have another set of those questions out curiosity sake, and these are dealing with the PowerColor HD 7990.

1) Can you crossfire two of these?
2) If they are crossfireable has it been done (are there any links or charts on performance)?
3) What size of PSU would you need if you crossfired (let’s say the CPU is an FX-8350)?

This is the card that I am curious about: http://www.newegg.com/Product/Product.aspx?Item=N82E16814131483&IsVirtualParent=1

Let's get started.

1. Yes, the 7990 is can be Crossfired, and that would mean that you have 4 GPUs on your system.
2. No, I haven't seen benches of Crossfired since that would be a really extreme setup. Expect a lot of heat, power consumption, and raw performance though
3. You'd want atleast 850 watts, but since the 7990 is a dual GPU card, it would be best to get 1000w

Tom's did a review on the 7990 and pit against the 690, here's the article:http://www.tomshardware.com/reviews/radeon-hd-7990-devil13-7970-x2,3329.html
