Ok, I've gotten to where I can't stand windows for very long at all, and want to run Linux most of the time on my desktop. The catch being, my desktop is my gaming machine. So, is there any performance hit you take when dual booting a machine? Do the extra partitions hurt anything?

(Sorry if this doesn't belong, I was unsure where it went, and figured since I was going to run XP, I'd post it here.)
