ok, so today is my b-day so i am getting all the money from that. so faar i have $200, but i still have some others that will give me some money. my parents are willing to put in about $175 so that is $375, and i will probably add a bit of my stash. (around $400 total). at the end of today i will find my total and perhaps order everything.
Don't commit yourself into getting one of the recommended builds from TechSpot, I only linked them as a guideline to what was possible for the money. As GeforcerFX has said you can probably build something with a different selection of parts that's almost as good or better in some aspects than the one from the TechSpot guide.
For instance some online retailers do "Combo" or "Barebones" kits which offer good value for money.
Newegg do
Kingston Genesis Blue/Phenom II X4 965 SuperCombo which includes a Radeon HD 6850 graphics card for $494.99 with $35.99 mail in rebates. The CPU isn't the latest and greatest but should do the job for gaming and that graphics card will let you run WoW and other games at their highest graphical settings(at least up to 1680x1050 resolution). For me I like to play games how they were designed to be played. Playing them with all the graphical options minimized seems almost an insult to the developers
If you end up with an AMD powered PC rather than and Intel you could try and balance out the cost of parts and get a motherboard that has the AM3+ chipset. This would allow for upgrade in the future to new AMD processors yet to be released.
The majority of games coming out now support multiple cores on CPUs so it is advisable to look at getting a Quad core (Intel i5/Phenom X4 or newer AMD processor). It's often a balancing act with money, for a gaming PC spend a little more on graphics card than processor, for a general purpose PC spend a little more on processor.
update: ok, i have $500. i could save and go for the more expensive setup, but is it really worth it? i would be saving lots of money if i got the cheaper one. Do you think i would be happy with the cheaper comp?
Really depends how much importance you put on graphics quality:

I used to have a low powered work laptop which I used for WoW when visiting a friend and my desktop PC is usually near to top end specifications.
Playing WoW with minimum settings on the laptop was visually almost like playing a completely different game from on the top end desktop PC. For me the immersion in the game world is more complete with the higher detail/higher graphic effect settings than with the basic settings.
