So, I'm trying to create a Build that will be a gaming rig.  The only problem is, I have a budget of $800 AFTER tax and S/H.  So far, this is what i have come up with....
 
1. $94.99 Case  
RAIDMAX Smilodon Extreme ATX-612WEBP Black SECC Steel ATX Mid Tower Computer Case 500W Power Supply - Retail    
 
2. $99.99 MoBo
EVGA 122-CK-NF66-T1 LGA 775 NVIDIA nForce 650i Ultra ATX Intel Motherboard - Retail  
 
3. 179.99 Video Card
XFX PVT88PYDF4 GeForce 8800GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Retail  
 
4. 199.99 CPU
Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor Model BX80570E8400 - Retail  
 
5. 84.99 RAM
CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X4096-6400C5 - Retail  
 
6. 59.99 Hard Drive
Western Digital Caviar RE2 WD1601ABYS 160GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM  
 
--------------
 
Now First, I don't know jack about Todays technology.  I used to build computers for friends about 6 years ago, but havn't in a long while and am out of the loop with the new technologys.  I have no idea if this setup is even viable. (Does it need cooling? Do they work together? am I missing something?)  
 
Dont' need optical drive/mouse/monitor/keyboard/soundcard.  Just the major parts listed.  
 
I probably won't be doing any overclocking, unless it's extremely simple, and I don't have to worry about it breaking down because of it.  The computer will be used for about 1-2 years before i purchase a newer/better one.  

Are you planning to use SLI. If not, go with a P35 mobo.

changed teh MoBo to this...
 
GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX All Solid Capacitor Intel Motherboard - Retail 89.99
 
 
considering i won't (at least i dont think..? ) be using SLI

^Good choice. If interested in OCing checkout:

Also make sure you get a good quality PSU.

Definately get a P35 like the DS3L if you don't plan on using SLI.
 
Also, I'd say get a slightly cheaper case like the Coolermaster 690 (great case for the $ IMO) and invest in a better PSU like the Antec Earthwatts.
