Ditto. That is the real question. It is great and all to have a 10.1 card but until developers pick up on it your no better than a 10.0 card. I'm more interested in what people are actually doing rather than what COULD be possible.
I think more importantly than DX10.1, I'm sure these cards are going to be a step up in performance (hopefully) over the 2900 in DX10.
I think DX10.1 is just the cherry on the top.
I've never really been a big ATI fan but I would like to see some competition and at least have a choice in the market of highend gaming cards.
