I think it is better to buy 2x7850 then, and adding two more later...
agreed
7850 is best buy if gaming isnt a concern, can be had for about $100 after selling games + rebate. resale value wont drop much below that in 2 months
Not sure if that's true, the MSI 7790 is $109 after rebate and before selling games (so take another 20-30 off), and can mine at 300k. Less power consumption, less heat, is quieter (fan only at 40-50% at fill 1200oc). These cards are wonderful, have 6 of them.
