What is best? Dual GeForce GTX 580 or Single Asus Ares?

Fastest out now is the GTX 580. having 2 of them in SLI is only good for "Bragging Rights" as there is no games out there at the moment that needs that much graphics. The Ares is a 5870 x2 with 4GB of RAM though its potential is great. it too, is more for "bragging rights" and at $1100 @ its WAY out of most peoples budget. if your into bragging rights get 2 Ares in Crossfire then get a HUGE PSU that has 2 sets of 8+8+6 pin connectors! Don't wast your money! even the old 460 can play Black ops well!!!!
