It's been very hard for me to get a handle on this issue of one gpu or dual cards. On the one hand, a single powerful gpu seems to be the most elegant solution (for gaming), but the "latest and greatest" gpus cost a million dollars. To offset this one can buy two lesser gpus and run them together either in SLI or Crossfire mode. Of the latter option it appears to be frought with scaling issues. I've read here and at other sim forums that getting dual cards to operate properly in our favorite genre is often a chore. My understanding is it's a matter of proper drivers from the card manufacturer. Based on that, one might very well opt for a single card.
Hopefully when SoW_Bob comes out there will be an adequate driver suite to run dual cards in that sim. Two 4870 in Crossfire would be very nice, and less expensive than the 4870X2 (but is that X2 at 2ghz of ramped gddr5 memory worth the cost, and willit show up as one card?). Does that, and the huge price drops put the GTX 280 in play? What to do?
