Help me upgrade this computer.

I was thinking of getting a new gfx card, or anyting else worth upgrading for my crappy dell. I have about $200 CAD to spend. Here are my specs:

Dell Dimension 8250
2.8 ghz p4 533 fsb
1gb pc 1066 RDRAM (thinking of adding more, but I cant find any)
9700tx 128mb AGP
250w power supply (I assume that may cause problems)

I'd recomend something like an X800GTO, X800XL, a 7600GS, or a 7600GT. The 7600GT is supposed to be available some time this month for AGP. You're going to have to upgrade to at least a 400w PSU.

Since he listed his budget as $200 CAD, one can only assume he's in Canada, and unfortunately New Egg doesn't ship there.

would zzf or tigerdirect ship to can
i have nothing against tigerdirect but have heard -things
never ordered from them

NCIX is the Newegg of canada. NCIX - Netlink Computers

Highly reccomended.

Edit: I'd be pretty hesistant about buying any hardware off ebay unless it was like an evga card that still carried the manufacturers lifetime warranty. You want to be able to RMA it if something goes wrong.
