To follow up on the "Build your own PC" thing, I think I'll elaborate. If you've never done it before and don't feel comfortable trying it out plug-n-play style, read this guide as you do it:
www.pcmech.com/byopc/For purchasing equipment, don't go through shops. They want to make money off of you, that's all. If they sell you that DDR4 ram for a gillion dollars, they make tons of money. You can easily get 4 gigs of quality DDR2 ram for 160$. Check out
www.mysuperpc.com and
www.mysuperpc.com/ram.shtml. (I mention RAM specifically because it's the easiest thing to upgrade)
Here's a sample PC for under 1000$ (the links to sites with these prices are available through the mysuperpc site, which I found fairly helpful... and stole most of my info from:
142.50$ Power Supply(500W)+Case
144.99$ AMD Athlon 64 X2 6400+ AM2 with Fan
51.99$ Zalman CNPS9500 AM2 Heat Sink and Fan (The AMD X2 6400 runs fairly hot, but with any non-generic heat sink/fan you'll get amazing speeds).
169.99$ ASUS M2N32-SLI Deluxe Wireless Edition (Motherboard) (AM2 Sockets)
39.99$*4 Crucial Ballistix 1G PC2-8500 DDR2 Ram
169.99$ eVGA GeForce 8800 GTS 320MB DDR3 Graphics Card
69.99$ Western Digital Caviar SE16 320GB 7200rpm SATA 300 MB/s
29.99$ Lite-On LightScribe Dual Formal Double Layer DVD RW/CDRW
Total: 939.40$
The audio from the motherboard isn't bad, so you don't really need a sound card. I'm not sure if you'll require a network card or wireless card, but that really has to do with your specific setup. Some accessories..
49.99$ Cambridge Soundworks PCWorks Multimedia Speaker System
18.99$ Plantronics Audio .90 Headset
You should be able to scrounge a monitor, keyboard and mouse from somewhere, otherwise a monitor could set you back as much as you'd like to spend on it, really. A cheap, used monitor from a thrift store really isn't going to give you a terrible gaming experience for the 10$ you throw at it, and a 400$ enhance premium super ultra excellent monitor isn't going to make your experience worth 390$ more. A good 100$ monitor would be fine:
Anyway, the specs for this PC are as follows:
AMD Athlon 64 X2 6400+ AM2 3.2 Ghz
320 GB hard drive, 300mb/s with a 16mb cache (huge)
eVGA GeForce 8800 GTS 320MB DDR3
4GB Ram -- 4 Crucial Ballistix 1G PC2-8500 DDR2 sticks
Probably running XP or Vista
Lite-On LightScribe Dual Format Double Layer DVD RW/CDRW (20x speed DVD writer)
Motherboard sound
Cambridge Soundworks PCWorks Multimedia Speaker System
Right now I have a ViewSonic 20" rapid response monitor that I got as a gift (I think they paid 100$ for it last year) and it works great.
My PC is nowhere near as cool as this, but for 1000$ (minus the parts that I have already) it's a great system, especially compared to Dell's 720$ system which doesn't even have a graphics card:
Inspiron™ Desktop 530
Intel® Core™2 Duo Processor E8200 (6MB L2 Cache,2.66GHz,1333FSB) (<3.2)
Genuine Windows Vista® Home Premium Service Pack 1 (160$ value)
3GB Dual Channel DDR2 SDRAM at 800MHz - 4 DIMMs (<4G, though to be fair XP/Vista often limits your max RAM to 3.0-3.5GB)
250GB Serial ATA Hard Drive (7200RPM) w/DataBurst Cache™ (<320, not as big a cache)
16X DVD+/-RW Drive (<20)
No Monitor
No Speaker System
--------Integrated Intel® Graphics Media Accelerator 3100-----------
