Wow seriously? That would be a very capable gaming machine with a discrete video card. You won't know yourself with a 750 ti in that rig.
2GB RAM is getting a little on the lean side so if you have the budget, get another 2GB stick (try to get the identical make/model and you should get dual channel mode). BUT, adding a video card will make faaaaaaaar more difference than an extra stick of RAM and should be your priority.
Do you have a budget? Because you could actually put a better GPU than a 750ti if your powersupply and budget support it.
