I bought an Asus desktop PC about a year ago for $550 with the intention of light gaming, but now the time has come for me upgrade it and I'm a little unsure of exactly I can put in it. The model is a CM1745-04. According system info it has an AMD A8 5500 APU with Radeon(tm) HD Graphics @ 3.2ghz, 12gb of DDR3 RAM, 1tb Hard Drive, and a 1gb Radeon HD 7470 graphics card. I want to upgrade the graphics card so I can play games at higher settings. My question is can I upgrade this system to an new and more powerful graphics card, If so which one without any bottleneck. Also when I find the right card, how would I go about upgrading it, specifically how to install it and keep the dual graphics built into the cpu.
PS: My budget is $120 and under.
-Thanks, Mike.
