Heres a good psy. always make sure you get a good well known brand. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003&Tpk=Corsair%2bPower%2bSupply

and here the best gpu for a budget http://www.newegg.com/Product/Product.aspx?Item=N82E16814129102

and heres my pick for the best gpu (pricewise) http://www.newegg.com/Product/Product.aspx?Item=N82E16814130318

and i doubt you can run games well. in fact it would be REALLY bad.

Antec Earthwatts 430W

Gigabyte HD 3850 512MB

If you can afford those,then you've got a killer PC,otherwise,your PC is garbage for playing newer games.
