Okay, so this is the first post I've put up. Before you laugh at my computer set up, realize that I won this in a raffle at my work for $5, and acquired some spare parts that were laying around (I work in the IT department).
It is an Optiplex 745 Mini-Tower.
It is a Core 2 Duo 2.13 Ghz machine with a Corsair 650W power supply and 7GB of DDR2 Ram, 1TB hard drive and Windows 7.
The max resolution is 1920 x 1080. I'd like to play at that res, but solid framerate is a priority. I don't mind buying a nicer video card to achieve that res, but I don't want to waste time or money and buy one and it rocks, but the CPU can't keep up with it.
