The only problem is the PSU is only 460 watts so please keep that in mind with the GPU suggestions.
This is the PC I use at my uncle's house when I have to housesit which has been quite often lately. I have been playing the new Tomb Raider with Post Processing turned off with no problems on the normal graphics setting at 1920x1080. But I do believe the GPU is holding this PC back from performing as best it can. I'm just looking for a GPU that would work well with this system without bottlenecking it. Thanks for any help/suggestions :)
I can't OC my uncle's PC because it is a pre-built PC from Dell. I added the 8800 GTS a couple years ago to his PC so I could play some games while housesitting.
