Talk me into or out of crossfire 7970s

Just built a new system with a 7970 which is a great card, I can pretty much max settings out in anything and get very decent FPS, but now I have the bug and feel like I want to max out settings AND fps.

Are there really that many games where I'm going to be able to use it? With the recent announcement that there's not going to be a DX12 anytime soon I gather a crossfire setup will last me some time with 7970s.

Do those crossfiring rate it? The money is not an issue but I don't like throwing it down the tubes so to speak.

I had crossfire 5850s and really rated it. Didn't have any of the horror stories you hear, the only headache was some games weren't supported "out of the box" and needed a new driver, though AMD seems to be pushing out quality desktop drivers very quickly these days.

I'd do it but only if I didn't have better things to do with the monies
 
I'm running 7970 crossfire and have no complaints! I've not had any micro stutter issues either. What res are you gaming at? I can max everything at 1920x1200, but you will really see the benefit at 1440p.
 
I'm only running at 1080p, what kind of performance increase are you seeing in general, I see a lot of people saying you're only going to get 30% or so but see benchmarks too which show 100% boost.
 
I'm running crossfire and I'm not having any issues at all... I'm going to be ordering 3 new monitors at the end of this week to run together and this is we're I'm expecting the crossfire to help with good settings and good fps.
 
I have just gone from 5870 crossfire to a single 7970, due to the fact I got really good money for them it was good for me but if I had played £400+ (water Cooled) I would have been a bit disappointed to be honest. Its a fast card don't get me wrong, but not a huge increase to justify the price you may pay. for instance the Heaven benchmark score stats as follows using the same settings as follows:
2560x1440 4xAA
Custom
High
Moderate

5870 Crossfire
FPS: 33.9
Score 855
Min FPS:8.3
Max FPS: 76.8

7970
FPS: 36.4
Score 918
Min FPS:17.7
Max FPS: 71.2

I havent done any official gaming benchmarks, but i can run Crysis 3 Ultra with MSAAx8 without a hitch. At 1080P i get just under 3400 in Unigine valley.

I went from 5870CF to 7970CF, so cant compare against a single 7970.

what about selling the 7970 and buying one of those new 7990?

I'm still mulling this over and I'm thinking that the 7990 might be a better idea all round, sticking with one card as I'm assuming it's going to work with more games? Edit: Though I read now the system sees it as crossfire?

I gather I would still need to get myself a new PSU for the 7990 as only currently have 500W.

Well Its still crossfire, But it uses cores that seem to be slightly improved so its not a bad deal.

sameish price against two 7970's according to news..., better performance than 7970 crossfire... I plan to get one if there is no news about the 8000 series.
 
I think to be honest I'll stick with the one 7970 until more advanced games come out, got Crysis 3 installed max settings and being one of the most hungry games It's still always 30+fps and usually around 45... Same with Tomb Raider everything max, at the moment don't think it's worth the extra >£300 for basically more fps.

As some of you are saying and others elsewhere It's not really a big deal at 1080p.

Thanks for all the answers :)
