So, I was looking for an upgrade to my Intel HD 3000 graphics, but I was not sure what to get. I know a fair bit about the computer's internals, but not anything such as compatibility and building a computer. I have an Acer Aspire AX3990-ES10P. It has 6GB of RAM, a 220w PSU, a 1.5 Terabyte hard drive, and a Intel i3 2120. I was looking for something that would allow me to play games at my native resolution (1600 x 900) on at least low settings. I play games like Call of Duty 4 and Battlefield 3, but I would like to get more frames per second out of my computer. So, if you guys could help me select a card, that would be great.
