Hi again
According to PC Gamers own "Hard Stuff" systems their systems build recommendations go after this ranking:
Sub-Entry system: Mid-range system:
CPU:AMD Athlon 64 3000+ $50 Duo CoreE6600 ( 2.4Ghz) $316
Memory:Corsair 1GB DDR-400 $104 Corsair 1GB DDR2-800 $109
Video:ATI Radeonx1600Pro 512M $125 Geforce 7950X2 $517
Case and PSU: 400 Watt/ATX 480W/ATX
Maybe some kind of a guideline and I myself do agree that what somebody else said is that 512 Meg memory sound "small" to me IMHO.
