Off shoot from e.allag's thread so what do you have under the hood.
The machine I'm running right now is getting up in the years, purchased in 2003 but its still very good. Looking and to get new quad core machine shortly.
CPU: Northwood 3.0ghz overclocked to 3.3
PSU: Antec TruPower 480watt supply
MB: Gigabyte P4 Titan - GA-8IPE1000 w/Intel 865PE Chip (this is one thing I wish I had purchased better unit)
RAM: 1024 MB Corsair PC-3200 XMS
Video Card: Leadtek A380 - GeforceFX 5950 256MB (this was replcement installed in spring of 04)
HD's: 2x 120GB Seagate 7200 SATA
This system is comparable to many of the low end systems offered now, not bad for 4 years.
