I have several computers I use, I have a laptop (five years old) for travel, presentations, email, and general stuff. I have an old Dell workstation - Precision 420 (seven years old) I use for web development and any CAD or analysis I need to run. I also have a mid range server for backups, network hub, and printer hosting. The Engineers Edge is not hosted on any of these computers BTW.

As you can see, I have had computing horse power problems. So I built the following performance computer:

Case: Cooler Master: CM Stacker RC-810
Power Supply: Antec NEO HE550
Processor: Athlon 64 X2 4400
Motherboard: DFI LANPARTY UT nF4 Ultra-D
Memory: 2x 1GB OCZ EL PC3200 Titanium
Hard Drive: Seagate Barracuda 7200.9 300GB SATA
Video Card: EVGA GeForce 7900GT 256MB CO Superclocked
Fan: Case Fan - ? 3" Off the shelf blows good
Monitor: Samsung 940bf 19" LCD
Sound Card: Creative Sound Blaster X-Fi XtremeMusic (why not)
Speakers: Logitech THX Z-5300e 5.1 Speakers
CD/DVD: 2X Memorex Dual Format / Double Layer max-500N
Mouse: Logitech G5 Laser Mouse
Keyboard: Logitec Elite LE
Operating System: Windows XP Pro

Now, those of you who recognize this hardware are saying "is'nt that a gaming setup?" - yes it is, however, it runs all of my CAD programs like champ - simultaneously... I'm actually surprised at how stable the machine is. I finally moved all of my applications from the old Dell workstation to my new computer Monday. I'll keep the old Dell workstation for just in case.
