My Garbage Computer

Dear /g/, I have a question. Several actually. I'm looking at upgrading my computer, but with it's current stats as follows, I'm wondering if it's just better to scrap it and build a new one:
Athlon XP 2800 (sucks)
Radeon 9600 (also sucks)
512 M Ram (utter shit)
240 Gb HD space (plenty)
DVD-RW (fine too)

So, with a generally crappy motherboard (No pci-e slots) What would you reccomend to get this hunk o' junk up to high-end gaming speed? How much would it cost?

AGP's on it's way out.  "high-end" might be out of reach without new board+GFX.  "decent" could be attainable with RAM upgrade to 2GB or so.

That being exactly my problem. Combine that with a shite processor to begin with, and it looks like I'd be better off just grabbing a new one with the processor already on. Any idea what would be best along those lines? Also, what graphics cards would you all reccommend. I often find it's hard to tell exactly what's the "best" out there.

>>1 is a whiner.

You aren't hardcore until you've used a 566mhz piece with a 4mb gfx card and 128mb of ram for six years.

>>4 is a whiner

You aren't hardcore until you've used a 120mhz piece with 2mb onboard video and 57mb of ram for twelve years.

>>5 is a whiner

You aren't hardcore until you've used a 66mhz piece with no onboard video and 32mb of ram for sixteen years.

>>6 is a whiner

You aren't hardcore until you've used a rusty XT with 80*24 bytes onboard video and 256kb of ram for twenty years.

LOL ownage.

Long live the cavemen!
