I'm living in South Korea right now.
I guess I should explain what I'm planning to use the machine for, that might help. I mainly just do office work for my job (word, excel, etc.), internet, downloading and watching TV shows, playing light games.
I'm hoping to be able to play better games with my new system, such as S.T.A.L.K.E.R., COD4, Bioshock, but not Crysis. I don't do any photo or video editing or anything heavy like that. I have done very minor audio editing (taking a short clip out of an mp3 for a presentation or whatnot).
My intended set-up is: Gigabyte P35 DS3P, C2D E4500 (maybe 8200 if the budget works out), 4GB (2x2GB) RAM, HD 3850, Zalman 600-watt PSU, and the other standard stuff.
