So I have a optiplex 740 big tower with a new graphics card. I play games on it mostly free mmorpgs and wow, and the one problem I have is the processor is way too slow. It's a AM2 socket processor and I've been told some am2 motherboards can be converted to work with am3 sockets which is what I'd like but this one cannot. Does anyone know of a cheap way to upgrade this motherboard and processor without changing out literally everything?
