I just recently built a computer for a Home Theater system but have decided to upgrade the graphics in it. I bought the Gigabyte GA-MA780G-UD3H motherboard with onboard ATI Radeon HD 3200 graphics which has worked great so far, but does not perform well with games. I have read and heard from many places and people that Crossfirex is not as good as just buying a high-end graphics card. I am not sure which graphics card would be best since I am relatively new to gaming. I have 4 GB of RAM, an AMD Athlon 64 X2 5200+ Dual Core processor overclocked to 3.14 GHz, a 500W power supply, and a 22" 720p Visio Television and a 1440x900 LG Monitor. Currently I run the TV with HDMI and the Monitor with RGB. Any cable setup will work, but I prefer keeping both monitors. Thanks in advance for any help.
