Well if money isn't a terrible issue I suggest you build yourself a nice rig...
The Comp I am building next year is this(BTW I am a gamer

):
CaseAntec P180 ATX Advanced Mid Tower Aluminum Case
Pleas Note that this case weighs 40lbs... so you might want to think of something else if you lug it around to LANParties alot.
Power SupplyAntex True Power 2.0 550W ATX12V V2.0 SLI 1200MM Fan Power Supply
This is a nice powerfull powersupply to handle SLI when I get the second video card
ProcessorAMD Athlon 64 3200+ 2.0Ghz
Planning to OC it eventually so I don't really need the 3700+
MotherboardASUS A8M-E Motherboard ATX S939 NFORCE4 Ultra DDR PCI-E16 2PCE1 3PCI SATA RAID Sound GBLAN
Onboard raid is pratical if you need it and Gigabit LAN is awsome (espicially when you are a staff at a LANParty and you are aloud to hook into the gigabit port on the switch

perks of the job)
VideocardEVGA E-GEFORCE 6600 300MHZ 256MB 128 BIT 550MHZ DDR PCI-E DVI-I TV-OUT Video Card
This is a nice Video card and hoping to get a second one like it to hook with SLI
MemoryCorsair Value Select PC3200 1GB 2X512MB DDR 400 184Pin DIMM DUal Channel Memory Kit
Memory is cheap and can always add more...
HardriveWestern Digital Raptor 74GB SATA 10000RPM 8MB 4.5MS Hard Drive
Might have a small capacity but note the RPM. I got a second 100GB 5400RMP Hardrive already for videos and stuff...
Optical DrivesSamsung SH-W162 16X DVD+-RW 5X Dual LAyer DVD Writer Black
Getting this drive x2 so that I can burn multiple DVDs at one time when I do my video editing for friends and family and can easily copy DVDs from one drive to another
Floppy DriveMitsumi FA404A-BK 7-In-1 Floppy Drive & Flash Reader
Never know when you will need a floppy drive and the Flash Reader is pratical for my digital camera
Operating SystemMicrosoft Windows XP Media Center Edition
Planning on getting a nice 32inch flap panel LCD or Plasma or maybe a projector so I can watch TV and stuff. Also already got the TV Tuner Card
KeyboardLogitech G15 Gaming Keyboard USB Clack Silver LCD Panel Programmable Back Lit Keys
Love this Keyboard...
Note that there is no mouse that is because it is already purchased it is a Logitec Corless Laser Mouse MX610. And also got the sound card and speakers. Creative Labs Sound Blaster Audigy 2 and Logitech X530 speakers.
Also buying an ASUS GIGAx1024P Smart 24-Port 10/100MBPS + 2-Port 1000MBPS Managed Rack-Mount Switch for LANParties and a LASER Samsung ML-1610 Personal Mono Laser Printer...
The grand total of all this not counting in the 70$ sound card, 130$(that I got on sale for 70$) speakers and 90$ (that I got on sale for 30$) comes up to 1639.09$CAD
All prices are quoted in Canadian Dollars and come from www.ncix.com
BTW I want two 17inch LCD Monitors but haven't decided with one yet.
