Is it worth updating an older computer, or is it cheaper to simply buy a new computer? I was given another computer, seems to work alright. I formatted and loaded Windows XP Pro on it. It has a 100 gig HD on it. But it seems slow, and has a hard time operating with more than 1 single window open. It's a Pentium II Processor, 348 MHz, 320 MB of RAM. Is it worth upgrading to a different processor with more ram? I haven't done anything with computers in quite a few years, so I'm well behind the times on what a decent computer is. All it will be used for is getting on the net, downloading, and ALOT of Photoshop work and digital imaging. Can I upgrade this myself for a decent price? Or is it cheaper to go buy a newer computer?
