i wouldent spend my money till febuary 07 when next gen come out. but if you do buy now, DO NOT PUT A SOCKET 940 PROC ON A 939 MOBO. if you even manage to socket it will fry when you try to turn it on. and dont waste your cash on a thousand dolar proc either. get an opteron 165 and a dfi lanparty ultra d sli. throw in 2gigs of lowly timed ddr500 memory, a 7900GTX a wd rapter, a large storage drive and a big psu. if want a fast disk drive the the plextor sata 2 drive. case dosnt mater but from personal experiance, dont cheap out to much and dont get an aspire case. get somthing all aluminum including front panel. also if you want to keep it quiet, get a case with all 120mm fans such as the gigabyte 3d aurora. (i buy mine in a couple weeks) and get a decent heatsink or water cool. oh and one more think, dont waste your time going sli right now. the 7900gtx will run everything just fine and your going to start bottlenecking your proc and you wont get the fps youd expect. the idea of sli is buy a nice card now and then when that card is $50 buy another one and be all caught up. that what Scalable means.
