Two 7970s will beat out one 780 in terms of theoretical performance.

The main problem with Crossfire is that as with all multi-GPU configuations, it can introduce issues like microstuttering and dropped/runt frames. In the past, Crossfire was pretty notorious for that kind of thing but AMD's new drivers have fixed most of those problems and now Crossfire is almost as good as SLI setups.

If you are going to go with crossfire, I would suggest looking at two R9 280X instead of 7970s. Basically the same price but slightly better performance.

The above poster is right the microstuttering is a issue with the higher end radeons then you have to take into account the heat of those 2 cards. So if it was me I would go with the 780 at this time.

Well that all depends on WHICH of the HD 7970s you're talking about. Sure, they might perform slightly better than the vanilla HD 7970 but not better than factory overclockers like mine. Also, the R9-280X comes with NO games while the HD 7970 comes with three. Those games all cost $50 each from steam so that's quite a value. I paid $510 after rebates for both of my Gigabyte Windforce overclocked HD 7970s and I got $300 worth of games. The games I chose? Here, I'll list them:

Tomb Raider 2013
Deus Ex: Human Revolution
Hitman: Absolution
Saints Row IV
Sleeping Dogs
Far Cry 3

I'd say that makes the HD 7970 more than worth it. :D

Are you speaking from experience or just parroting what another site said? As the above poster also said, the new drivers have fixed a lot of those problems. I'm running that setup right now and I have zero issues.

NO I have 2 7770 radeons so yes I have experiance and also I have a 7950 at times while gaming I will see a slow down or a stutter with the rad 7770 but its only for a few secs But it happens from my own experiance and I do know the 7950 radeon ghost card from XFX gets really warm toasty so yes from experiance before we get into case air cooling trust me my computers are well ventalated with massive fans such as 240 mm to 140 and 120 mm fans.. and btw I have all AMD SYSTEMS still waiting till they pull a rabbit out of there arse until the first of the year before I switch camps myself...
