Looking for a cheap sli motherboard for socket am3 or 3+.I have 2 gtx 275 cards but my current motherboard has only 1 16x slot and a 4x slot.I still need to get a power supply I dont think my corsair 600 watt is enough.Might overclock a bit since my amd 820 does just fine at 3.2 ghz but not trying to max it.This is a super ultra cheap build and i'm doing great keeping it under 400.00 so far.Current system is Asrock A700DE+,amd Phenom 2 820,6 gb ram and gtx 275.I know this stuff is old now but my next build will be Intel but for now I'm gonna spin the wheel and see what happens ty.
