Well, I've got a crossfire motherboard, bought it *for* crossfire, have the one x1950pro which doesn't need any special cables or ought, just plug in and attatch a bridge... and my new sexy 22" monitor is lovely, but I haven't run any intensive games, and I'm not sure how it will react if I try to run stalker at max settings at 1680 x 1050. So thinking, might pop another x1950pro in there. But with dx10 cards round the corner, it doesn't seem worth it. I guess I could re-sell them...
For that matter, what would be better. Two medium range cards, or one high end card? I mean, with hard drives, you could say 2 250gb hard drives (if you have the space) are better than 1 500gb, because they'll be much much cheaper. And I am on quite a strict budget .
My only concern is that when dx10 comes out, dx9 cards might plummet in value so I won't be able to flog it (or them, if I get another)
