I need everything, MOBO, Memory, Graphics, Cooling.. Eveything.
So, even though I already (pretty much) know what I am going to get, I would like to know what you think I should get. For $800 what is the best possible gaming computer I can build?
Thanks a lot for answering everyone!

Building a gaming machine isnt hard. Just look google “building pc” “how to build pc” or something like that. Thats what i did and i sure did end up building a nice computer.

I need to build a list of video games and casual gaming trade shows and conventions scheduled for 2007, can you please point me to a resource where i can find such details and also any advise on how I can go ahead in preparing such a list.
Thanks a million.

Also what operating system do you recommend? What Graphics Card to?
