Ok, so I spoke too soon...my bad.
I am now trying the trial version (what else can you do with one, eh?
). It seems to me that this just changes the application priority handling of xp (this is just a surmise, I may be wrong here). When I used it, my cpu usage increased slightly from what it was, so I imagine it allows apps to get more of a chumk of the processing power than xp normally gives them. But, the point is, the original query was concerned with OC'ing and speeder xp has nothing to do with that. Still maybe Indie-Lover might want to try it out. Though, personally, this is an app I won't purchase...
