6850 it's a mid-range card in the current generation from ATI and to reach the high end performance, I would need 2 of these in CrossFire - around GTX580. Now, a class, like mid-range or high end or low end (to relative cover them all), does not mean it describes only one product, but rather an interval of performance in which a large variety of products can be found. 67xx series is going to be just some 57xx cards renamed, basically, you're going to be in the same performance area as I am for this generation, depending on specific cases .
By the time Skyrim would hit the shelves, the next gen should already be on the market, probably the high end of these days at the available price of mid-range cards; win-win situation.
also 'I can drive two 22" displays at high settings', sounds like a monster card to me, not a budget setup.
To be honest, I'm surprised of the FPS this card can hit on such a big resolution,
but games are not that demanding anymore - general speaking. Plugging the second monitor in Oblivion made little to no difference in frame rates. Also, the card can't run a graphics intensive game in full details, AA, AF @ 60 FPS. Keep that in mind.
PS: The value of components from my rig, might be as "high" as a brand new PS3. It ain't that expensive, now is it?
