<b><font color=red><i>First thing to learn in building a PC is to never get in a hurry</b></font color=red></i>. I'm sure you can build your own much cheaper, and learn a whole bunch while doing it (maybe have so much fun that you will become a nerd
), but you must attain your first goal: <b>Build the PC first</b>.
After you complete your first goal, you will have plenty of time to learn how to overclock. Just like you are doing now...seeking information. There are a lot of smart people here in THC forum who will answer your questions concerning OC'ing. Here is some rational information on <A HREF="http://www4.tomshardware.com/guides/overclocking/index.html" target="_new">Overclocking</A>, or take it up a notch and visit: <A HREF="http://www.overclockercafe.com/Reviews/Cool View Window/" target="_new">Overclocker Cafe</A>. Couple this with visiting the OC forums above with questions and you will start to understand what to do and what not to do.
If you are seriously thinking of taking the challenge of building you own system.
1. Then, make a list of hardware you will want to meet your need, i.e., (PC for gaming, PC for graphic work, or PC for office apps).
2. Read reviews; like, of course here @ THG, <A HREF="http://www.anandtech.com/" target="_new">Anadtech</A> and, <A HREF="http://www.storagereview.com/" target="_new">StorageReview</A>
3. Ask questions in forms like THG, Anandtech.
4. Shop for the price range of your budget <A HREF="http://www.newegg.com/" target="_new">Newegg</A>, <A HREF="http://www.pricewatch.com/" target="_new">Pricewatch</A>...etc.
5. Follow all the instructions, and continue to ask question when you get stuck.
There is no price tag on gaining experience by learning, and as the saying goes..."if at first you don't succeed, then try, try again." This is only my personal viewpoint, but the decision is your.
