Hey guys . im stuck between either upgrading my gpu or cpu and i cant afford both.should i upgrade my amd fx 8350 to a 4930k extreme and an asus P9X79 Intel X79 motherboard. or upgrade my gpu from a gtx 670 ftw edition to a 780 ti? . Which would benefit me more for gaming and rendering videos for youtube etc as iv just started youtubing. i only have a 600 w corsair psu so i dont really want to SLI. any adivce please?
