I currently have a fairly old comp im wanting to upgrade for alittle bit of better gaming experience. some specs = celeron(r) 3.07GHz processor 512ram pc3200 ddr 400MHz SiS661fx graphics I recently ordered 2 1gig pc3200 ddr 400MHz to carry alil more load. Will they pose any known problems I should be aware of? Also is it worth the trouble of doing minor overclocking to that processor... or just a waste of time? Thanks for any advice.
