Go get yourself a decent video card
Sapphire ATI Radeon X800 SE Video Card,
256MB DDR, 256-Bit, DVI/TV-Out, 8X AGP,
Model "102-A26126-00-AT" -OEM for $310.50 at Newegg.

Use part of the rest of your money to max out your system RAM.

With $5 of the money, go get a blowjob from a Thai whore.

With what's left, either get yourself a 200+GB hard drive,
or get yourself a GBA at a pawn shop ($40 or so), a flash
cart through the internet, and a 6 DVD set of GBA goodies
($30 or so).

For your money you will have a faster overall PC
experience, plenty of games to play on a handheld, and a
wanker that's spent.
