askcv - you haven't told us what you have in your beige box of tricks. It might not be worth shelling out 100 or so notes on a spangly new video card, if you've only got a Pentium 200 MHz and 32Mb RAM - it would have the same effect as putting twin Webers in a Robin Reliant, ie not a lot. (Read something like a Hyundai Compact in USA)
If, on the other hand, you've bought it recently and been ripped off by a box mover who has put cheapo parts into an otherwise high spec machine, then it would definitely be worth it. Putting a cheap, sh!tty video card in would be like disabling the turbo in a Ferrari. Looks good, but not giving its best performance.
BTW, if you did buy the machine recently, and you made it plain at the time of ordering that you wanted to be able to play games on on it, you MIGHT wish to press to test. Here in UK, we have a clause in our "Sale of Goods Act" about "Goods not of merchantable quality", ie, they can't do what they're supposed to be able to do. I'm sure you have similar if not more stringent consumer protection laws to ours. For example, if you ordered a joystick with it, it's pretty bleedin' obvious you wanted to play games.
Back to the question, then, post brief details of your system spec, and more worthwhile advice will no doubt wing its way to you from the members of ABCLP (Arcane Brotherhood of Computer-Literate PPRuNers)
