DX9 and DX10 performance compared

DX9 and DX10 performance compared:

"So, it seems, there is some difference to crow about - although it is our suspicion that, given the time and inclination, most of the flasher DX10 features could be retro-fitted without much hassle, and the differences are more a product of time and money than capability.

...

The conclusion is that not only do ATI and Nvidia share identical image quality (certainly something to be pleased about) but also that 512MB is swiftly becoming the new minimum spec for cards when talking about DX10 compatibility at any resolution above 1280x1024. All those effects need them some memory space, we suspect."
