hey guys, I just sold my xfire 6970s and bought an r9 290 ( non x ) what a beast, buts the 6970s to shame and overclocks great, now I want another one to crossfire, I've read around trying to figure out if I need a bigger power supply and can get a straight answer. right now I have a cooler master silent pro M 850w psu bronze cert. im running this with an overclocked 3570k. will this psu be enough to run 2 290s or do I need to go bigger, if so whats the reason. some people say an 850 is good enough depending on the quality. also if I need a bigger psu ill just go huge and get a 3rd 290 in the future. what are your thoughts for a psu for 2 cards and or 3 290s,
