Nvidia GTX 590 or AMD Radeon HD 6990?

hd6990 or ASUS MARS 2

Lol ASUS MARS 2 only bill gates can afford that XD.

Well ASUS MARS 2 is the best single card gpu.

Ok so if you cant live without PhysX then GTX 590 is the way to go.

Now the HD 6990 is a tiny bit faster, bigger and is very loud (So they say....)

The GTX 590 is 2 under clocked GTX 580 or you can say 2 570s, the 590 is smaller quieter and they say it has heating troubles.

Now i was going with a GTX 590, but then changed my mind to either 2 HD 6970s or 2 HD 6950s.

Which i guess is better than the 590,

Hope i helped
