I'm just looking to buy a very good GPU which I won't need to upgrade for a long time and I can't decide between these three. I don't know the exact prices of them but I know they are all very expensive.

I also need to know if my phenom II x6 1090t will be enough to run along these GPUs. (3.2Ghz 6 core not OC'ed)

So which should I chose? Comparing price and performance if possible :p

Not really an apples to apples comparison, you've got the 7990 and the MARS III, which are both dual-GPU cards, up against a single-GPU R9 290X. The 7990 will be the fastest, with the MARS III coming second, and the 290X bringing up the rear. But the performance of the dual-GPU cards solely depend on how well a particular game supports/utilizes dual-GPUs. There are still a few games out there that will only see one GPU, but fortunately I don't think those games are very demanding, you could probably max them with one GPU. Pricing will reflect upon performance, with the 7990 at the top and the 290X at the bottom.

Depending on the release price of the MARS III, it may or may not be a good buy. One thing for sure though, it will be more...

Depending on the release price of the MARS III, it may or may not be a good buy. One thing for sure though, it will be more expensive than a pair of GTX 760s because of the custom PCB and the extra work that went into designing the card, as well as an upgraded memory bus. The MARS III should be priced just under the 780Ti, while being slightly faster, stock vs. stock. But it will be quite a special piece of hardware, something uncommon that you can brag about.

The 290X doesn't have a very good cooler at the moment, I wouldn't go for that until aftermarket versions with better coolers hit the market. But if you're willing to spend some extra bucks for an aftermarket cooler of your own, there are a few out there like the Arctic Accelero that has been proven to work with the 290X, and makes it much more practical.

The 7990 is simply a beast in every way, unfortunately. It has huge performance figures, but that also comes with huge power draw, heat, noise, and size. Like the 290X, it's also hot and loud, but it'll be tricky to find aftermarket cooling for it due to its dual-GPU design. I would probably stay away from it.

Thanks for the amazing answer!!

If I get the 290X without buying an aftermarket cooler, the only bad thing it'll have is noise and heat? No risk of overheating or anything that might damage it? Same for the 7990

Actually with the rise in price for the r9 290X its about the same as a GTX 780ti(I know its not listed but still), because to get the full performance out of the card you would need to get a partner of AMD's remake of it. Where as the GTX 780ti is fine with its original cooler on.

This thread was started before the 780 Ti was released, and at the time the 290x wasn't so expensive.
