    How much are you spending on that 7990? Performance is brilliant btw, really depends on how much you're sending on it and where you're buying it from

    650$, couldn't you get a 290X for that price, possibly even two reference R9 290's since I think they are around 300$ in price though it was a while since I checked.
    (And I might be mistaking it for the R9 280 which is basically a 7970 so the 7990 would be better if that's how it is.)

    There are plenty of games that do not work well with crossfire or not at all.

    Now consider the fact that a 7970 is quite a weak card, and thats what you'll be playing a lot of games with...

    Not worth it unless you only play games 1 month after release.

    7970 (280X) a weak card? What has the world become? :bang:

    Sure it's previous generation, but it's still FAR from being a weak card.

    To OP, if you can, I would rather grab two R9 290 (Non X) which should be available for close to that price and it'll offer you a lot more.

    I would first OC your cpu and see how much more you get out of your CFX setup. We have similar systems and after seeing the Asus 32" 4K monitor locally, I started thinking about a 7990 or 290x CFx upgrade too. Maybe add a 3rd 6950/70 but my last slot is 4x so won't bother.

    Instead I am testing games using downsampling on my setup - force 3840x2160 down to 1080p to see if my cards can handle it. It works for some games so far so long as I turn off AA but can use some FXAA or SMAA. Arma 2/3, DayZ mod version, UE2.5/3 engine games, but no Crysis 3, Metro LL or BF3/4 games (too slow).

    2x 290 CFX would be good bet for ~ 600 USD.

    +1 I recommend getting the r9-290 and another one down the road later.

    What in the hell are you smoking? I dont see a crossfire rig in your sig atm so who are you state on that anyways? Amd has been doing a sh*t ton better with crossfire profiles and driver releases. Not even 1 7850 is a weak card. Quit being a damn tosser.

    I have a sapphire 7990 and the only issues I've had with this card is that there is some coil whine noise but not terrible. The Other top issue is that I cant get this card to go above 120Hz without crashing with crossfire enabled but disabling one card will allow you to play at 144hz without blue screen crashes. Only solution which isn't possible for 7990 is to add another crossfire bridge. So unless your playing 120hz and with headphones it would be a great investment because performance is great!!

    nonsense. Crossfire support is really good nowadays, there's games out there that support crossfire before SLI. also crossfire scaling is better in general than SLI scaling.

    Nothing wrong with the 7990, I wouldn't spend $650 on it though.

    hi all ty for the replys im currently looking in to this situation
    a r9 290x is starting from $639
    and a r9 290 is $525 so i think that this hd7990 is maybe a good deal for the price..
    as in the benkmarks and the reviews it performs well over the r9 single cards...
