I have a custom computer that my uncle gave to me, but i want a gpu upgrade. Right now I have a ATI 5450 Mobility, which sucks when I am playing any game. I want to get a new computer but I cannot afford it right now.
In order to upgrade, I want to replace my GPU with a GTX 650 Ti Boost. I am not very sure if an i3 2120 will bottleneck it. I am upgrading my PSU to a Corsair GS 600V2 (preparing for my future build) from a 420W generic psu. Currently I have around $380 AUD, minus around $150 for a headset and mouse. So I basically only have $230 for an upgrade.
