Do you need 4gigs of ram on a desktop machine though?
Well a few years ago I would have laughed at you but seeing how 2gigs actually makes a difference in Vista due to the improved memory management, I’d have consider going for it… If it didn’t mean I had to scrap my 4* 512 stick… But I guess even that’s off the table until people stop faffing around with 32bit desktop applications and decide they’re bored of it.
