I've seen a single 7970 play ultra settings on far cry 3 and battlefield 3 on 1920x1080.Is Dual AMD Radeon HD 7970 good enough for Ultra settings on Battlefield 4 ?For Battlefield 4 can you just give me a opinion if dual 7970s can play it on Ultra settings on 2560x1080.is Dual 7970s good to put ultra settings on Far cry 3,Tomb Raider,Hitman Series,Resident Evil Series,The Assasins Creed Series,And more.Is Dual 7970s good enough to max every AAA game thats gonna come the next following year and the new AAA Games that are about to come out?By the way the resolution i wanna play on is 2560x1080.If the 7970s are good enough for 2560x1080 ultra settings on every AAA thats gonna come out and every AAA thats already out.

Even a single card should Max it fine, but dual 7970 are better than a 7990.

2560x1080? you might want to double check that resolution, what monitor is that? Since introducing a second card for AMD's crossfire introduces stuttering, you can often end up with negligible performance increase, and increased stuttering, by the time the frames hit the monitor. They have recently introduced a driver update that partially fixes this, at the cost of cpu overhead, and lower fps scaling. If it were me, i would suggest to keep the 7970 till they release their next gen cards, or sell it and switch to a better performing nvidia card/cards.

Both perform about the same. While both the 7990 and 7970s in crossfire seem to behave erratically in this review, this is because of driver issues rather than hardware differences:

In answer to your questions about peformance, as the review shows, these cards can currently run all games out there at max settings in 1440p, so you should be fine.

Since both card have about the same amount of grunt, it's really going to come down to whether you want one dual-GPU card or two cards in crossfire. If your case can fit two 7970s and handle the airflow, then two after-market cooled HD 7970s are probably the better option. They can most likely be overclocked to a higher level than a 7990 since, on that card, the two GPUs share one heatsink. Make sure you've got a motherboard and power supply that can support this, though.
