OK, I was looking to either upgrade my system or start from scratch. I'd like to keep my budget around $1,000 - $1,500. I'm looking for a pc to do some gaming. Mostly into Everquest II and World of Warcraft. Here is what I currently have. Otherwise using it to browse the web and run some basic applications. Here is what I currently have available to me.

Amd Athlon XP processor
LG Dvd Burner 16X10X40
Case with 450 watts max
Geforce 7600 graphics cards
ATI Rage 128 ultra graphics cards
MSI motherboard
A Data Memory expert 1gb
Westinghouse 16"

I'm looking for some advice and am open to suggestions. You guys helped me out last year, now I'm looking to help someone else.

i would suggest upping the mobo to a p45...and ditching the 9800gt, better performance for the same price using a 4850. the upgrade of a mobo with a p45 vs p43 is about 10 bucks and coupling that witha 4850 will allow you to run crossfire in the future, if you ever decide to play something more graphically intense. The proc gators chose will be a good one especially if your running lots of online games as it allows more tasks simultaneously.
id say asus p5q pro, but deluxe if you want to overclock

gpu like this saphire. http://www.newegg.com/Product/Prod [...] 6814102770
an antc neopower modular psu http://www.newegg.com/Product/Prod [...] 6817371010
that'll still leave plenty of room for nice monitor (with hdcp cap. if you ever plan on getting blu-ray) and even a nice case if you want...

I would actually take a different approach on with this since your gaming will not be very graphic intensive:

CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Chan
http://www.newegg.com/Product/Prod [...] 6820145184

MSI KA780G AM2+/AM2 AMD 780G HDMI
bundled with
AMD Athlon X2 4850e 2.5GHz

Acer P243WAid Black-Silver 24" 2ms(GTG) HDMI Widescreen LCD Monitor

OCZ ModXStream Pro OCZ600MXSP 600W PSU bundled with Western Digital Caviar SE16 WD6400AAKS 640GB

LITE-ON 20X DVD±R DVD Burner with Nero 7
http://www.newegg.com/Product/Prod [...] 6827106264

SAPPHIRE 100245L Radeon HD 4850 512MB
http://www.newegg.com/Product/Prod [...] 6814102770

Microsoft Windows Vista Home Premium SP1 64-bit
http://www.newegg.com/Product/Prod [...] 6832116488

Total = $974.42 - $80 MIR = $894.62

You can recycle your case but if you want a new case go with:
Antec Three Hundred
http://www.newegg.com/Product/Prod [...] ntec%20300

or a

COOLER MASTER Centurion 534 RC-534-SKN2-GP
http://www.newegg.com/Product/Prod [...] 6811119104

Either way, the cost will be an additional $50-55 if you do decide to add case.

Edit: They seemed to have removed the $30 instant savings off the Corsair ram. Go with this instead:
mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800
http://www.newegg.com/Product/Prod [...] 6820146692
This change adds an additional $15 to the build

Thank you all for your suggestion. I'm going to run it by my friend later on today.
