i'd be needing too somewhere along the line get a i7 system, but i'm not entirely sure which motherboard to take yet. there is also the thing of which psu to stick in there of the coming 260gtx for now.
Or otherwise go for the stock Intelx58 "Smackover" generic board or ECS BlackSeries which supports SLi,CrossFireX and as far as i remember it supports 6 x DDR.
