System in Specs with a NEC FE991SB 19" monitor, logitech mx510 and logitech wireless keyboard. I think i'm going to an sli setup, or an a64 939 non-sli setup soon to replace this one (even though i don't think i need it sli considering i barely game.) What price would you sell it for, i think he only has $740 plus i don't want to jip him, is that enough?
