This computer specs are a bit odd...
AMD Athlon 64 X2 5000+
4GB DDR2 PC800 (generic - I forgot the name of it)
ATi Radeon HD4670 1GB
LG HD DVD/Blu Ray Combo Drive
3.5 Media Reader
COOLER MASTER eXtreme Power Plus RS-500-PCAR-A3 500W
1TB Samsung HD
Mainly use it for surfing the net and some media shit like watching the TV, music, movies... looks great on my ghetto entertainment setup :P
The sound is missing from the list since the sound I use is the onboard stuff, and my TV doesn't have HDMI audio, and I don't have a HDMI receiver, since I only have an el cheapo 2.1 receiver. Going to add a 1.5TB HDD and another optical drive (just DVD). Was going to get a 1GB 4850, but I decided against it since I don't do much PC gaming these days, so it'd be wasted money, but I REALLY wanted the features on the HD 4XXX series, and I wasn't too impressed with anything below the 4670.
I have some P4 2.5Ghz machine back home... and a laptop that is busted that I don't really care about the specs. I know it had a Turion 64 and a Geforce 7000m onboard, the display is busted.
