I have tried the windows versions of the later betas (183,184), and they both have this problem. The thing is, Exdeath, that 2.08GHz is by no means slow. As you go up in processor speed, the performance boost is less and less noticable, unless you have 20 or so programs running in addition to the normal background programs. While 2.08GHz isn't the fastest on the market, it is much faster than what you could get just a few years ago.
