always a good place to start. if you can reuse the tower put that money into a better cpu.
Thank you for that link, while I still had no idea what I was reading it gave me insight i guess :/
I did a little research and it looks like all that really matters for a gaming desktop is the graphics card. Okay so my idea was to get either a dell inspiron 660 (~$300) or if I really want to stretch the budget an X51 alien ware (~$650), the latter which is probably out of the question. I was then going to just purchase a really nice graphics card like a AMD Radeon 7xxx series, or Nivida GTX series. Would this be a good idea, and would it work with an inspirion? How can I tell if a graphics card will be compatible?
