I need some advice. I currently have a NVIDIA GeForce 210 in my system, but some games like Dead Island run like poo. I thought that maybe I could upgrade the video card and get some better performance, but I'm not really sure which one to get. As I understand it you want to pair your video card based on your processor and motherboard's performance otherwise if you buy too good of one it could be bottlenecked by other components in the system. Any advice on what would be the best graphics card to upgrade this system for descent games?
Processor: AMD Athlon 64 LE-1660
Memory: 4 gb PC2-6400
Power Supply: Not sure on the power supply though.
