My fiancee just got a tax refund for about $1200 and wants to use it to buy a new computer. She wants to go to Fry's today to shop. We've been talking about a new computer for her for a while, since her current one is an old Pentium II machine running Windows 98 on a 6GB hard drive. I'm going to help her build it, but I'm a little out of touch with the current components on the market. What components would you recommend that are good quality, run most games reasonably well, and all costs under $1200?
