I want to upgrade my old gpu to a newer and better one, the one i currently have is a Nvidia GeForce GT130.I am planing to get myself a GTX750TI Asus with 2 gigs of ddr5.My current gpu consumes 350W and the gtx750ti uses 150W.Will it work with my pc? My other components are 4 gigs of ram, q6600 @2,4GHz (4 cores), a Gigabyte G31M-S2L motherboard and 500W psu. Will it work?
