Read http://www.tomshardware.com/2007/05/01/the_best_gaming_video_cards_for_the_money/ and see if you picked one from their list.
"First of all, will any graphics card work ok? Or does it need to be a particular configuration to suit my PC? What are the things I need to see if they are compatible with my PC when looking for a graphics card?"
Yes. The units you picked appear to be 3 PCIe and the third one is an AGP. You need to figure out which your machine supports. Also some machines need a power supply upgrade.
Since you neglected our forum note I can't answer which one would possibly work (agp or pcie).
Here's the forum note you should see when posting.

I'm looking to buy a graphics card for my pc. My current one is rubbish! First of all, will any graphics card work ok? Or does it need to be a particular configuration to suit my PC? What are the things I need to see if they are compatible with my PC when looking for a graphics card?
Secondly, is there any difference between a graphics adapter and graphics card?
Thirdly, I've shortlisted these graphic cards/adapters. Which is the one I should go for? I'm looking for one that basically lets me play the latest games at high FPS. Thanks!
