out of the cards you listed and I hate to say it because I prefer Nvidia cards over AMD. But the 6870 is good for the money. Out of the Nvidia cards don't get the GTX 550 Ti's you will not like them I know I have two of them in SLI on my rig. Some where here on Tom's web site they have a chart to compair graphic cards. It I find it I will repost it so you can check it out for yourself. Inless someone else can do it for me. When it comes to games it is how fast your gpu is and other stuff that works with it like memory etc.
