Processor choice - which to go for?
I am trying to decide on which processor to get for a close relative's PC, but I'm not sure which one to go for. I know this is a much-debated topic, but I just want a couple of opinions. I'm looking for something powerful enough to run the latest games, office applications (minimum load time), and possibly an image editing app like Photoshop (although if it's good enough for the latest games then I'm sure it won't have a problem with that). I'm not looking for something too expensive, but a good all-rounder for a desktop.
I'm slightly wary or 64-bit processors, because as much as I'd love my relative to run Linux on the PC, that's not going to happen any time soon - and I'm sure there are still quite a few Windows apps which do not work on 64-bit systems. So, I could go for a 64-bit processor and run 32-bit Windows XP so that all apps can be run, but then I'll be losing the 64-bit functionality. However, if I go for a 64-bit processor (like AMD's Athlon 64) with 64-bit XP, I run the risk of my relative not being able to run her favourite apps.
Any help greatly appreciated. :D
Thanks,
