Hard to say for sure, but my numbers are really good. The problem is I have card variance. One card overclocks core 1225+ and mem 6000+ on a VDDC offset of only 131. While the second card overclocks to core 1180+ and mem 6000+ on a VDDC offset of 145. One card needs little voltage the other needs a lot. So I have to unsync them (voltage-wise). After that the sweet-spot took a little while to find. I game with both cards OC-ed to 1140 and 6000 with VDDC offsets of 75 and 106. 3D mark scores at stock - Firestrike extreme 9260 and at overclock 9400+, over 9522 once, but was unstable clocked on the core at 1160. One thing to note. I have these in PCIe 3.0 x16 and x8 slots. The performance would be slightly higher if both were x16.

Yes it will be enough, you could even run it in crossfire and not see a bottleneck.

If you want to crossfire the gpu's then I would not recommend this power supply. If you are only running one gpu then this power supply would definitely suit your needs.

The HD7970 is a rebranded R9 280x thus it should have no problem running in crossfire.

Yes supports crossfire pro and it runs in a 3.0 slot mine is running just fine

Yes. You can run these in crossfire. No cable or extra software required. Two cards will show four cards total displayed in your OS.

No because this is an nvidia cards crossfire will only work with 7950s but the video ram can be different and the brand can as be different but it is best to pair identical cards

According to my experience with the Asus M5A97, it'll work more than perfectly. As a matter of fact, you can get two to try crossfire! The only thing you should worry about is the power supply of your computer because you want enough to support the graphics card and everything else.

This is actually a 7970 ghz edition card rebranded as a 280x. So it is much better than a 270x. You can crossfire a 280x with a 7970 ghz or even a 270x or below down to a 7850 card. That makes this card very versatile. I have two 280x's in crossfire powering three 27 inch 2560x1440 monitors in eyefinity. 45fps in crysis 3 on ultra. Very smooth. I love this card especially the price.

yes, you can cross fire any 2 7970's, but the faster card will be throttled down to match the slower one and will only use the amount of ram on the smaller card.

Hello Pizurro, AMD and XFX website recommends 600w PSU, but depending on the cards, HDD and other components on your RIG a 500w is fair enough. For Crossfire you'll definitively need a 750w.

No It does not come with a crossfire cable, you will have to buy one separately.

No, crossfire is AMD Radeon technology. Check out AMD's website http://sites.amd.com/us/game/technology/Pages/crossfirex.aspx for more information.

I personally regret not going with the M5A99 for 2 reasons. I already had 2 Nvidia cards I planned to SLI and found out this board only supports cross fire. One of the sata ports is blocked by my video card so I am limited in adding drives since I am already using 4 ports.

I actually don't know. I would start with the AMD site and see what information you can find there. If you can't find any helpful info, then I would try Newegg. If you still can't find it, call AMD directly and ask where you can purchase one at. I wish I could be more helpful, but I'm only running a single R7 graphics card and I am not utilizing the crossfire feature.

What would you like to know about a CF set up? I have it set up in CF and my brother has it crossfired with a 7950. Both setups are far beyond optimal graphics with not a single issue yet... coolest crossfired cards I've ever owned.

I run the 100psi crossfires on my semi. You can find the 80psi crossfires on Amazon or chromshopmafia.com. I strongly recommend them.
