I am looking at moving from my am3 setup to an i7. I just dont know if its worth it now or if I should wait. I can get a i7 950 from microcenter for $200 and an evga 3 way sli board for another $200 at microcenter. I can get ram to fill it and have some for whats left of this pc for $90 on here. Then I am looking at another GTX 275 maybe but that could wait. Thing is will a Antec Earthwatts 750 be enough for an OCed 950, 12gb ddr3 SLI gtx 275s (possibly a 3rd later) and several drives? I also would need a case, preferably a full tower but something not so pricey if possible.
