My case is a SFF - so they would have to be low profile cards
My psu is 280 SFF - its a rare power supply and 280 is the highest out there on the market, so it's non-upgradable
I have two expansion slots, but only one of them are PCI, and its on the wrong side, so i wouldn't have space for graphic cards that are two expansion slots wide like the 7750
I have Core 2 Duo E6550 - its fine for gaming
I have 3GB ram - its alright
