No i mean memory rams
I'm pretty sure you have no idea what you are talking about. Thats not bad, but you should probably do some reading or post a picture.
You want to 1) buy the Corsair 400CX for $39 on newegg, then 2) get a 4670 graphic card. Its a great value at about $60 online.
If you wanted to spend more you could get a better graphic card with that power supply, but how much you spend on that is entirely dependent on how serious you are about gaming.
