I always build my own, but I design complicated 3d stuff on my PC, latest 1 is water cooled and geared for CAD not games. Dell and HP make very competeitive machines on price but they are absolute Pony, I used to fix PC`s for my mates until I got cheesed off with constantly going round burning my own fuel and not getting my own stuff done because Dells are just that bad. They put on a lot of emulating software rather than building the proper hardware so although the specs match up in the real world a proper PC willl thrash the pants off it as there is more CPU run time available, try running a test using something like 3D mark on a Dell and then on a self-build which on paper is the same spec. When you do a self build you will also load less software on which will load less shite in the tray (beside the clock) and leave more CPU available again. Now I just build specials for like minded CAD people that need the power.
update before I even post the post, went to dells website and looked at their cheapest PC, went to my online supplier (
www.ebuyer.co.uk ) and added up at their costs and it was £26 cheaper, OK so you don`t get the software with mine but I have a cakebox full of it and Dell and all the others will virtually not pay for software at all, and Intel will sell them CPU`s 75% cheaper than they will sell it to me, and at the end of the day, its not a Dell.
My spec if anybody is interested, just finished building a water cooled nightmare by the way,
ThermalTake Tsunami Case (no lights or anything),
3GHz P4 overclocked to 4.5, 800FSB means I have 2 CPU`s,
2GB GEil RAM,
2X 74GB raptors in RAID 1 system disk,
400Gb lazy disk for films etc,
LG DVD RW,
Nvidia 6800 GT that thinks its a Quadro 3500,
ABIT Motherboard,
Lots of copper blocks I made at work, 6 Litre resovior, tubing etc.
