I need to buy a new graphics card. The fan went out on my old one, tried to fix, but it didn't help. Went online to get another card like the one I have, but it seems to be obsolete. So I figured I would just upgrade, but don't know how to figure out what I need. My system specs are as follows: Intel(R) Core(TM) i5-3570K CPU @3.40GHZ; Windows 7 Home Premium, SP1; 8GB ram; Terabyte HD. I do have a PCIe x16(2.0) slot, a 500W power supply. My MB is a Biostar H61MHB, my ram is 2DDR3. My system was built by CyberPower. Looking for a graphics card between $100-$200. Thanks for your help.
