I just finished my last build, a Quad Core CPU.
I never used a PC based on this CPU. I have been using Pentium 4 from 2000 to 2015 and after this an AMD A6-6310 CPU.
The purpose of this system is to run games that I can't run with my other build, a Pentium 4 @ 3,4GHz based PC.
CPU: Intel Xeon E5440. 
Mainboard: Asus P5B.
RAM: 8GB (4x2GB DIMM).
HDD: 2x500GB (SATA II, 7200RPM).
DVD: Samsung DVDRW (IDE).
GPU: Gigabyte Nvidia GTX 280. 
PSU: Enermax Maxpro 600W.
Chassis: Chenbro PC61733 (big and heavy box with two 12cm chassis fun)
The 'only' things that I bought are CPU, mainboard, RAM, GPU and power supply. I already had the rest of the components.
Why I decided for this specs?
- To continue with the CPU Intel timeline and cover the gap from Pentium 4 to the firsts Core I3 / I5.
- The PC must be a complete Windows XP compatible and works well with Windows 7.
- Since it will be dedicated to games the GPU are an important election but I don't have previous knowledge about this. Because of this I've started reading reviews in magazines, in this forum of course, wikipedia, etc and the Nvidia GTX 280 seems to be a good choice, not the better but enough for me.
- The parts are not too expensive.
In this moment I'm installing Windows XP 64 bits...
