If you are curious about it, just look up reviews of the 6870 and see how well it fares on games like Crysis, Metro 2033 and Civilization 5/Unigine Heaven (for tessellation) at your resolution. If you take those games as being the current high-end, then you can somewhat gauge what sort of frame rate you may get 2 years down the line. Do bear in mind a lot of games these days are either console ports or multiplatform so they generally won't be as demanding as the few games I mentioned previously.
They're all the same reference design, so they're all going to be pretty much the same. Only the factory overlclocked cards with custom coolers are going to be worth the extra money. So then for me, it comes down to warranty and customer service (if you ever have to deal with them).
A lot of people prefer Asus over the other brands as they generally come out with "better" cards, but looking at the 6870's on *CAN'T POST LINKS-REFER TO ORIGINAL POST*, their "overclocked" version is only a measly 15MHz which is laughable.
I know XFX have a double lifetime warranty which means not only do you get a lifetime warranty, but if you resell it, the buyer will get a lifetime warranty too. I don't know if it's worth the extra price though also considering a lot of people complain about XFX's RMA service.
Scan's page doesn't seem to mention how long each of the manufacturer's warranty are, but try to find out which is the longest and just go with whichever is within a reasonable price. If they're all the same, then the Gigabyte (cheapest one on Scan) should be fine.
