Ok, so i plan on building a computer of my own, havent bought anything for it yet but i want to make sure that everything is compatable. also if there is something cheaper that will help me save money but play WoW smoothly. Ok well heres the list of everything i plan on buying excluding case;

Asus M3N72-D Motherboard
AM Athlong 64X2 6000T Processor
Corsaid Dual Channel Twin X 4096MB PC6400 DDR2 Memory(2)
Seagate Barracuda 1.5TB HP
XFX Geforce 9800GTX Videocard
Creative Lab X-FI Titanium Fatal1ty Pro PCLE
Ultra X3 ULT

Looks alot like my system

Asus M2E
AMD 64 X2 6000 cpu
6 gb Corsair memory
Nvidia 8600 GPU
Coolmaster Case upgraded PSU to Thermaltake 450W

OS: Windows 7 (64-bit)

Monitor Viewsonic 1640 X 1080

Absolutely 0 video lag, even in besieged

You definately aren't saving money if you're building a rig to run WoW smoothly. And unless you plan to do some heavy media storage, 1.5TB is overkill.

You can get away with a 2.7Ghz AMD Dual Core for 1/2 the price of the one you've go listed, shave about $70-80 off the Mobo, you definately don't need 8 gigs of Memory (and many system configurations don't even work properly without tweaking above 4 gigs). 9800GTX is overkill as well (you can get away with a 9400 GT, it will run WoW on high settings). And you can certainly power a system like this with something like the 550 watt Fatal1ty power supply, which is nice because of it's modular design.

Kill the sound card, too. Most ASUS boards come with at least 5.1 onboard. There's no need to spend money on a PCI space taken up that does the same exact thing with more driver complication and heat exchange in your case. All in all, you could save hundreds.
