The 730 is the lowest recommended gaming card, will run most games but newer ones at Low. No info about the CPU, that makes a difference also. 7 gig of RAM is an odd amount, looks like the system was pieced together. I'm guessing that's a dual channel not a triple channel system, you should have either 4 gig, 6 gig with two 2 gig sticks and two 1 gig sticks or 8 gig for optimal RAM speeds.
