Just finished building my first system last night.
Intel Core 2 Quad Q9550 (overclocked to 3.8GHz from 2.83GHz currently)
Coolermaster Hyper212 CPU cooler
Gigabyte EP45T-EXTREME Motherboard
ATI Radeon HD4890 Graphics (currently overclocked to 950MHz core and 1050MHz memory from 850MHz core and 975MHz memory)
NZXT Tempest Case
Antec Earthwatts 750w PSU
GSkill Trident DDR3 1600MHz 8-8-8-24
LG DVD Burner
Seagate 500GB Hard Drive
Asus VH232H 23" Monitor
Sorry for the camera quality...



...and a pic of my overclock, with a stress test running in the background.

I reckon I could push this CPU to 4.4GHz or so, but I am very happy with 3.8 at this point.

This is awesome. :DDDD
