Normally I game at 720p, because my current gpu and cpu combo can't handle higher resolution at payable FPS. For the games that it can handle such as DOTA 2 and CS: GO play at my monitor's native resolution of 1440x900 and I don't intend to game at high resolution and maxed out settings.. as longs as I can have good fps at medium settings it would be good enough. As you mentioned I will upgrade the cpu after few months but as of now just looking at not spending too much to assemble a whole new rig all together..
