I recently bought a system but got laid off before I could buy a 670 :-( anyways I have a 3570k as rock extreme 4 z77 8 gb or ram looking for a cheap fix for my graphics solution. I have a chance to get two 6770 for 100$. As of right now I'm running off the hd4000 just looking for something to get me by until I can afford the 670. Should I get the two or just buy a $100 card performance wise which would be better ?
Two Radeon HD 6770 in CrossFire should be similar in performance to a single Radeon HD 7850.
For two Radeon HD 6770 in CrossFire AMD specifies a minimum of an 600 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 32 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.
