Around 1200 USD for my i7 920, MSI Eclipse mobo, GTX 260, 3x2 gigs ram for it. I had already my case and PSU, a sound card I'm fond of, speakers and monitor I like (or am at least content with) The case was close to $200 USD when I bought it (tt Armor +), the PSU $190 (PC Power and cooling silencer 750), the Speakers $99 (M-Audio Studiopro 3), the monitor was about $180, the sound card $90 (Asus Xonar DX). I guess I also own a G15 keyboard, a G5 Mouse, and a G13 gamepad, a Plantronics Gamecom 377 headset...hmmm about $2250 USD over the long haul. Though a lot of the components I had already, I spent $1200 in Dec. on the mobo, cpu, gpu, memory, and OS that makes it into the computer it is today, the other stuff I already had.
