I have scanned some archives, but cannot find a definative answer for my question. I am running a windows xp based system with 3ghz processor and 1 gig of ram. I may sound greedy, but I want better performance on photoshop, and running a couple of applications at once. I have a pretty heavy workload, and the computer suffers greatly. Will adding another 2 or 3 bg of ram be enough to increase speed and performance on photoshop, whilst other applications are running, or do I need a faster, dual core processor? Would 64 bit help. I'm not enough of a geek to understand to much technical terms, but any info would be a help.
