OK under 950 i'll tell you a few stuff for gaming most important are CPU not under 2.4 Video Card and memory all other less important i would suggest something like
CPU: AMD 2600 - 2800
MotherBoard: Gigabyte, ASUS or Abit (i don't remember if ASUS have MBs for AMD) dual channel ofcourse
RAM: 1GIG 512x2 Samsung or kingston not less than 1GIG
Video Card ATI Radeon 9600XT even i like Nvidia i do recommend that or Nvidia FX5900XT i checked it out not bad at all now company Leadtek, ASUS or gainward(leadtek only Nvidia they don't make ATI never checked gainward but i know they suppose to be good)
HDD about 120G SATA if you can affort try getting less space but 10k RPM (10000RPM)
Monitor LG or Samsung or sony 17" atleast Flat if you got money get LCD but it is expensive
what else hmm
CDRW:Teac Or Philips or Plextor (both has 2 years warranty)
