Query: Incredible, but be ready to work for it.

I am an experienced windows user, and I bought this book because I figured it was cheaper than upgrading my PC. I run a K6 266 overclocked to 300, 160 megs of ram, 7200 RPM 27 Gig HD. Once I implemented ALL of the tricks in this book (This is no easy task... it takes a lot of time, and is very high maintenance), my system out performed my ex-girlfriend's Pentium III 850 with 128 megs of ram for applications (not for games, though it still does those well).I don't mind making the effort, but some people might. If you have lots of time, and you love customizing your PC, you can't go wrong.Litestep, registry hacks, DOS utils, 5 partitions on a HD... if you like this kind of stuff, get the book! If you don't know what any of these things are, you may be better off upgrading you PC.
