If you are looking for a fairly decent desktop system, and you happen to be near a Micro Center store, you should look into the HP Pavilion p6710f that’s on sale for just $390. The p6710f is powered by AMD Athlon™ II 640, a quad core processor.
It comes with 4GB DDR3-1333 RAM, 1 TB 7,200 RPM hard drive, an ATI RadeonTM HD 4200 display card, and powered by Microsoft Windows 7 Home Premium (64 bit). You can review all the details of the p6710f at Micro Center’s website. I think it’s a great deal.
I would get this if I were looking into buying a new system, but I already own a AMD Athlon™ II 640 system. I could use more memory and a better graphics card, but this system for the price is a great deal.
