Any suggestions for a gpu upgrades that would run with that psu?
Safest bet is the 7750 800Mhz. But if you can afford it, I also suggest upgrade to a decent power supply because what you have is basically of unknown quality to us. The basis for a GPU upgrade should be what is your resolution, games your play, desired settings & target fps. Limiting your choice to what your PSU can support may work but maybe cause for disappointment & need for another upgrade, hence extra expense.
