If you bought it in a local shop, you could return all and get back with a working system (e.g. RAM, CPU and mobo, and return with the same CPU with a compatible mobo and RAM). There are way newer chipsets then the aging nVidia 590, look at the newer chipsets like the 760FX. Gigabyte MA790FX-DS4 and DS5 are outstanding boards. Only thing you can’t use is SLI, but crossfire you can (ATI). Also the video card is going to be replaced soon by the new GTS, even the 8800GT kick’s *ss with the "older" GTS.
