All hardcore gamers will soon be going Vista though for DX10.
Not me for a while yet, As much as I'm raring to have a crack at Crysis which looks amazing and is a step forward, I've not seen enough difference between DX9 and DX10 in several large articles doing the rounds on the net in terms of Crysis alone
Not enough for me to justify spending £lots on upgrading, theres also no guarantees that the GTS320Mb version will really cut it in the performance stakes and some techy sites still aren't 100% convinced that any current DX10 card will allow smooth gameplay at 1600x1200 with AA/AF maxed out and all the eye candy maxed out
I'd also want to wait until the inevitable Crysis 1st patch rolls out and also at least 1 revision of graphics drivers after either Nvidia/ATI have a mainsteam DX10 game to relate to
As much as I want Crysis to be a huge leap, after the hype surrounding the shambolic laughable mess which is STALKER, Think I'll play it DX9 to start with, see if it's a good game, keep an eye on the DX10 feedback and wait til after xmas before upgrading
