I was thinking about cheapest components for my gtx 670 so they would not bottleneck the card. I have Corsair TX 650W atm, and OK case (but without usb3.0 front panel). Other components, which i use now (e6300 cpu, some old mobo and old ram) are to be bought. I don't want over powered, just to let gtx670 work good. I found i5-3350P processor so far. What would you recommend thou?
