Re: Thinking of dual booting with linux
Sorry to disappoint you up front, but I can almost guarantee wine WON'T support all the games you're playing (unless you're addicted to minesweeper?) It's great for what it is, and it can support some 3D games now (which seems pretty amazing considering I remember around the time it first ran notepad successfully!) but it's never going to be a finished product. Cadega is Wine's "paid for" gaming counterpart, but again that only supports a few select games. What it does however it does rather well!
If you're willing to try other games, there's plenty of open source ones around, but chances are they're not what you're playing at the moment.
If I haven't put you off, Ubuntu would be a good starting point, it sets up pretty much everything for you and its hardware detection is pretty damn good these days. Suse is another good alternative if you're not happy with Ubuntu.
