What upgrades should I get?????

I have about 250 dollars to spend on my computer. What upgrades should I get?

2.8 ghz dual-core

2 gigs of ram

Geforce 6600 vidoe card with 512 mb

350 watt power supply.

Windows xp

I saw on Newegg.com had video card/powersupply combo. Are any of those a good deal. I plan on buying from Newegg.com. What is my best bet for getting the most for my money. By the way I mostly pplay FPS's.

You could do this 9800GTX for ~130 and use the rest for a good PSU, probably want atleast 550watts

i'd go for a new GPU and aybe somemore RAM. If you were looking on the long term you may want to upgrade your processor depending on the one u have already.
