I want to upgrade my PC. Right now I have an AMD XP 2700+, ATI 9600XT AIW, 250gb HD, Sony DVD burner, Asus mobo, 512mb Patriot RAM PC3200 all in an Anted SOHO case w/ 400w PSU. I would like to spend around $400 max $450 on a processor and mobo and then use the other parts I already have. I would like to get a 939 pin AMD 64 and I am not sure about what mobo to get. Any suggestion what mobo and processor do you guy think would be best. Thanks, Ety
