AGP is the slot that video cards use on the motherboards. A motherboard will have one AGP slot and a few PCI slots for other cards (Modem, network, etc)
A new type of slot called PCI-Express has been developed that is set to replace the use of AGP/PCI motherboard slots. PCI-Express is relativley faster, and more importantly can carry more data between the CPU and the cards connected to the motherboard. Larger pipe = better performance being the idea.

As a larger pipe so to speak would mean that video cards could be sent more data per second, that could improve their performance. Realizing this, Video card makers have been some of the fastest to adopt this emerging standard. PCI-Express based motherboards can still use all your old PCI cards like the network and modem, but they now have the a different slot for the video card. So PCI-E is backwards compatible with PCI, but not with AGP, Got all that

Here is a comparable PCI-E card to the AGP card you pointed out. I like This one more, but it's about $10.00 more. I admit I like it more becuase I like ATI based (non-se) products, and have never owned a GeForce based product. In that sense, I am ignorant to compare them.

For what you listed playing, all these cards work fine so far, including the one you pointed out.
