If a demo of a video game works on your computer, will that necessarily mean that the regular game will work?

Question

I am contemplating on downloading a demo for a popular computer game. If the demo works on my computer, will the regular game work on my computer without having to buy another $150 graphics card?

BTW, my graphics card is a NVIDIA 6600 and the video game in question is Call of Duty 4.

There are three good answers here and I can't decide which one is the best so I'm going to put this question to vote.

Vote for the answer that best suits your own opinion!

Answer 1

Here's what I found, you're running on minimum requirements so it should work

" Recommended Specs
CPU: 2.4 GHz dual core or better is recommended
RAM: 1GB for XP; 2GB for Vista is recommended
Harddrive: 8GB of free hard drive space
Video card: 3.0 Shader Support recommended. Nvidia Geforce 7800 or better or ATI Radeon X1800 or better

Minimum Specs
CPU: Intel(R) Pentium(R) 4 2.4 GHz or AMD(R) Athlon(TM) 64 2800+ processor or any 1.8Ghz Dual Core Processor or better supported
RAM: 512MB RAM (768MB for Windows Vista)
Harddrive: 8GB of free hard drive space
Video card (generic): NVIDIA(R) Geforce(TM) 6600 or better or ATI(R) Radeon(R) 9800Pro or better "

Answer 2

There is no exact answer to this question, it's a 50-50 chance. A long time ago, i had download the demo for Halo 1. I enjoyed it, so i decided to buy it. When i bought and ran on it on my computer, it was terrible. It was slow and just bad. There were NO scratches on the disc at all and i had a friend check it and there were problems with the disc just my computer. But you have a awesome graphics card in my preference and Call Of Duty 4 should work fine on your computer.
