How long are the 58XX series and where's the power connection? I had one of those "oh shi*" moments when installing my GTX 260 as it didn't look like it would fit. It did fit in the end, but only just and it's a good job the power connector was on top of the card.
I'll wait and see how the price/performance/noise measurements work out. Buying brand new tech is almost always a mug's game.

) - I want a solid product that will do the job. I basically buy BFG rather than NVidia as they have REALLY looked after me in the past with RMA returns. When I have to buy something other than BFG I have tended to buy XFX ATI 4870 cards as they allow you to transfer the warranty.
. that said X2 release is in november so maybe they will come up with a better cooling solution can but hope.
