I have 4 slots total and useing 2. So you realy think a new mobo and cpu is what my focus should be right now? If I do say get a asus mobo or something and slap 512 in it with maybe a 2GHz, useing my current ATI 9200 do you think id get more preformance out of the card? or sould I also need a new card.

Edit: I thought I remembered seeing 4 RAM slots but when i see my board on the site, it obviousely only has 3, wow my board is old.
