A very nice Liquid Cooler. LC's are a must for gaming rigs, cpu fans do not cut it anymore.

Buy new: $345.95 / Used from: $169.00
I choose the Q6600 over the Q9xxx series because while those are faster. this one is more overclockable. Some people have gotten this one to over 4 GHZ.

Buy new: $90.55 / Used from: $59.99
You dont really need this because the Motherboard comes with a x-fi sound card, but lets just say it goes bad, or you want to buy a sound card anyway. Creative's sound blaster series are some of the best cards on the market at the time of their releases. X-Fi's are great cards and they can put out massive sound.
Logitech G11 Gaming Keyboard (Black/Silver)Logitech G11 Gaming Keyboard (Black/Silver)
Buy new: $79.99 / Used from: $48.00
I chose the G11 over the G15 for one simple reason. This keyboard gives you 54 programmable G keys while the g15 gives you only 18. Sure the lcd screen is an alright feature, but its pretty much useless.

You get 7 programmable keys: two thumb buttons, the left and right mouse buttons, and the scroll wheel is a 4-in-1 deal. the up down scroll, but it also moves from side to side for side scrolling.
X3 1000-WATT Modular PsuX3 1000-WATT Modular Psu
Buy new: $399.99 / Used from: $219.99
if your going to use ANY kind of latest card from ATI or Nvidia then your going to need this power supply, if you going to use sli or cross/quad (for the X2's) fire you will need the 1600 watt version. Modular so you dont have to connect what you don't need, its the end of case spaghetti as we know it.

Oem might not be your thing, but it gets you vista for cheap cash. Most fo the myths relating to oem Os's are not true. You can only have this installed on one computer, but you can reinstall it as many times as regular OS's (i think Microsoft's limit is 5 before you have to call them to reactivate).

Buy new: $139.88
an awesome speaker set. I have 2 connected to my computer (effectively 10.2 surround ;P) using splitters and extension cables off my X-fi card.

Raidmax Shark-wsb CaseRaidmax Shark-wsb Case
This would be my second choice for a case. I own Raidmax's sirius case and it is an airflow titan. Keeps my 3.4 ghz p4 cpu temp below 40C idle, and below 57C during full load.

Buy used from: $400.00
This is the most powerful video card on the market today. It's almost unbeatable in all games it has been tested in. If you have the money, get two of these for quad fire. it will make your gaming experience even better. --Edit replaced the Diamond version with Sapphire due to its much lower cost.
