I'm thinking about reformatting and putting Vista on. I have a legitimate copy of RC1 from Windows that I've never used. I use my computer for web design purposes, Dreamweaver, Photoshop, Cinema 4d, etc and games (mostly counter strike source). Does anyone here use it and are there any known problems with running games (like cs source and the applications ive described aboved) and vista? Is it worth upgrading or should I just reformat with xp pro? Thanks guys...
