Just out of curiosity, have you already got those two R9 285s? Because that's a bad place to start if you're looking to get the best graphics for you money. If you already have them, fine... but if this is a planned purchase, or you have one and are planning to buy another, it's definitely worth posting your current build, budget and upgrade plans here, because it's very likely you can do better with your budget.
