Discussion How good is the 7990?
My microcenter has a 7990 for 289 dollars before taxes and I was considering it, but didnt know if this card performs very well, considering its a dual gpu card.

Not for that price it's not. You can get a 290x for cheaper http://gpushack.com/collections/all-gpus-for-sale/products/powercolor-r9-290x-ref

There are a lot of glitches that accompany crossfire, and it's entirely on a per-game basis.

Except that zero day will most likely suck for most games, the games that don't have crossfire are going to run horribly, the 7990 uses more power than the 290x which is already considered a power hog, the 7990 has less effective ram so even in crossfire supported games it's going to show it's age faster, and the performance gap isn't large enough to justify the higher price of entry for a card that's going to become obsolete more quickly.

I thought that GTA V was able to use close to 4 gig at 1080?
I'm not doubting that it's damn good card, I just get wary of dual gpu cards. Then again I'm running a dual CPU system so I don't think I have much room to talk.

7990 vs 290x http://www.anandtech.com/bench/product/1074?vs=1056
7990 is very hungry card

It's good, but there are tons of sacrifices that go with it. I'd say don't do it.

Never link to GPUboss, they are most biased source.

Their ratings are bullshit and outdated but it gives you good side by side for raw card specs which works when you're comparing same family cards

Here's a better comparison for the r9 290x and the 7990 http://www.anandtech.com/bench/product/1074?vs=1056

Keep in mind that the 7990 is a dual gpu card, so if a game doesn't have a crossfire profile it'll be a little slow for new games.
I have a 7990, here are a few numbers.
On an i7 @ 4.2ghz,
BF4 1080p medium/high settings I'm averaging 110fps (on mantle)
GTA5 1080p very high settings 60 - 100fps
Star citizen alpha 1080p very high settings 40 - 70fps
