Thanks for the response, but I am able to figure out the economics of this. My dilemma, I guess, is really that I have been looking, and the 285 is still selling in the > $200 and even > $300 price range (although I do see them selling used on ebay for less). Is it still that great of a processor that it is worth bridging two of these v.s. buying a newer-series GTX, probably bridging two of these, eventually. As these are still so pricey, does this mean that this really is that great of a card? Because I know there is normally a very dramatic drop in price after a processor has been on the market for, say six months, or so.
If it wasn't for seeing how expensive these GPUs still are, I would have no doubts that the current-generation cards are much better.
