i'm gonna run a single gtx 600 along with an FX 4130, 2 hard drives and 5 120mm fans. For this setup, does a GS600 worth extra $20 or should i just get corsair CX600? please dont refer antec or seasonic, its not available here. i can only get cooler master or corsair and i chose to go with vorsair. also, if i had to go with cooler master, would a GXII 550 be enough?
