The Hushed Casket was founded in 2002 shortly after the launch of the XBOX console. Today the Hushed Casket is a thriving community of gamers, playing together and publishing news and stories that have appeared in major media properties like Newsweek, G4TV, USA Today, and Penny Arcade. Some game developers have even referenced our guides and news to support their gamers. We don't play Halo. We LAN Halo.

Here's my pick for a $800
Here's my pick for a $800 build. Total is $786 shipped, leaving you a few $ for misc expenses. There's also a $30 MIR on the video card.
Samsung DVD burner. Didn't see much difference between all the optical drives.
Rosewill case with 400W PSU. Rosewill is Newegg's house brand. They're generally reputable. I would go to Tom's hardware and look up power requirement's of each component to verify 400W will cut the mustard with some room to spare.
Western Digital 500GB HD. I don't need 500GB, but for an extra $30 over a HD with half the space, it seems like a no-brainer.
EVGA 8800GT video card. I'm not the brightest bulb in the tanning bed when it comes to video cards. I went strictly by reviews and awards. This one got a customer's choice award, looks solid, and fits in the budget nicely.
A-DATA 4GB RAM. This is DDR2, 800Mhz RAM. Great deal for 4 GB. However, you can only get 3 GB usable out of 32-bit versions of XP and Vista. The extra gig doesn't hurt since it all comes on 2 sticks.
Gigabyte mobo. Very highly rated, won customer's choice award, and nicely priced. Has optical and coaxial audio out in for easily connecting to a 5.1/6.1/7.1 surround sound system. All solid capacitors, which is apparently good, although I confess I don't know why.
Intel Core 2 Duo 3.0 GHz 45nm processor. 45nm chip will run cooler and allow you to overclock more. A quad core chip is within your budget, but I don't think it's necessary.
CPU cooler. Picked a modestly priced but highly rated cooler for socket 775 chips. Don't know much about it.
I think the PSU is the weakest link of the build. Reviews say it's good for a basic build, but nothing extravagant. If I were going to add to the build anywhere I'd go with a different case and better PSU, but I think the build is solid as listed.
What do you guys with more experience think? Have I made any stupid errors on compatibility?
