I've researched for about a week now, and I've come down to a point that I may need some help with my rig. And I figured this seems like a hospitable site (I hope). Here's what I have so far:

Newegg.com - Pioneer Black 20X DVD+R 8X DVD+RW 10X DVD+R DL 20X DVD-R 6X DVD-RW 16X DVD-ROM 40X CD-R 32X CD-RW 40X CD-ROM 2MB Cache SATA 20X DVD±R DVD Burner - CD / DVD Burners $31.99

Newegg.com - RAIDMAX SMILODON ATX-612WBP Black 1.0mm SECC Steel ATX Mid Tower Foldout MB Computer Case With 500W Power Supply - Computer Cases $94.99 (I'm uneasy about the PSU that it comes with, not sure if it will hold up with my build.)

Newegg.com - Seagate Barracuda 7200.10 ST3250410AS 250GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - Internal Hard Drives $59.99

Newegg.com - Acer X193W+BD Black 19" 5ms Widescreen LCD Monitor 300 cd/m2 2000:1 (ACM) - LCD Monitors $159.99

Newegg.com - BIOSTAR TForce TF8200 A2+ AM2+/AM2 NVIDIA GeForce 8200 HDMI ATX AMD Motherboard - AMD Motherboards $89.99

Newegg.com - EVGA 512-P3-N861-AR GeForce 9600 GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards $124.99

Newegg.com - A-DATA 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory 45.99

Newegg.com - AMD Athlon 64 X2 6000+ Windsor 3.0GHz 2 x 1MB L2 Cache Socket AM2 125W Dual-Core Processor - Processors $112.99

Newegg.com - Microsoft Windows XP Home With SP2B for System Builders 1 Pack - Operating Systems $84.99

Newegg.com - Saitek PZ30AU Black 104 Normal Keys 4 Function Keys USB Wired Standard Eclipse Keyboard - Keyboards $34.99

Newegg.com - Microsoft N71-00007S Black 3 Buttons 1 x Wheel USB Wired Optical Wheel Mouse - Mouse $9.99

Brings to a total of about $850. Any ways I can improve upon this? I'm hoping I can bring it down to an even $800, but I don't mind paying a little bit more ($50) to be on the safe side. Thanks in advance for the help.

P.S. Build is meant for Overclocked gaming.
