What to look for in a video/graphics card?

None of your links are working , can you just list the cpu and motherboard? The general rule is to buy the most card for the money you have available. The cards that you listed are all Nvidia cards , does that mean you only want Nvidia cards?

MSI N560GTX Twin Frozr II/OC GeForce GTX 560 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
$199.99 and a $20 rebate makes it $179.99

Both of these cards are in your budget range and would work with your build. There are more to choose from here;

However!

ZOTAC AMP! ZT-50302-10M GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

After posting all of the other cards I found this one which is much better than the 560 and would be the best choice , the 560Ti is a much better card and will give you very good performance and after the rebate it fits in your budget.

EVGA 01G-P3-1561-KR GeForce GTX 560 Ti FPB (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

I know it's a little over budget but this is also a very good card and I believe worth the extra $20 over budget.

Your links don't work. It's easier to just list your parts anyways since we don't want to have to click on all of them.

The first thing most important, is the chipset. Then Coreclock. Also you want a DDR5 card, not a DDR3 card, even if the DDR3 card has twice the memory. The DDR5 card will still be faster.

When you say this is mainly for playing WoW. Is that really what you will be doing? This matters because WoW is a processor intensive game, you don't need a crazy powerful graphics card to still get good fps/quality of image. However, if theres the chance you might be playing some of the newer/other titles.. IE: bf3 etc etc. Then that changes what you want to get. For WoW my personal suggestion is stick with Nvidia *tends to work better specifically for that game* and don't get anything better then the GTX 560 *have seen multiple posts/feedback it produces 200 fps in wow*. Anything else would simply be over kill. Why shoot a rabbit with an elephant gun  

Yes, it's mostly for playing World of Warcraft (WOW) and here is what my specs are with out links

I just at least want to be able to run it on Good Settings, i may end up playing Diablo lll, later on possibly others, but i'm not worried about ULTRA, OR SUPER HIGH Settings. Thanks, everyone for the info so far, anymore info would be very well appreciated.

Also INZONE i have looked at multiple sites for video/graphics cards and i haven't found any radeon's that are 2.0, i know 2.1's will work with my motherboard, but not at optimal performance, i want something that is gonna work and still do a decent job without me having to upgrade a ton, i could but rather spend money on the kids or something  

Thanks for all the info everyone.
