i currently have the rig in my sig. do you think i should upgrade the CPU from the a64 3500+ to a dual core? maybe add another gig of ram? i use the machine for downloading and games, and occaisional photo editing. the current rig works fine now, just a few skips here and there, but like any tech crazy guy, im looking for more. i was thinking along the lines of an x2 3800 or 4200. i looked at core 2 duo, but ive only had this rig since august, and id rather not have to completely upgrade. your thoughts?
