Well I got the gtx570 evga and am wondering if I should step up to gtx 580? I do not want to go sli right now, cause the power supply just wont cut it and I do not want to buy a new one at this time. I have 65 days left, pull trigger or wait and see if something comes out better closer to that time. I haven't heard of anything coming out soon, so it would be nice to enjoy the better card. Just do not want to miss on something if possible.
