Which Radeon HD 6870?

The reference design cards are all the same. So if looking at non-reference designs you should look at value, cooler design, and features that you want. Read some reviews on the cards you like if you're looking for reliability.

I don't know why the XFX cards should be an issue because they have a double lifetime warranty. No one else is gonna give you that.

HIS Radeon 6870, a great card recommended by many senior members

The Twin Frozr II by MSI is quiet and runs cool.
