The ultimate FSX Graphics card??

Hi Allcott, Just wondered from where you took the information that FSX 'does not support CrossFire'. The whole marketing advantage of CrossFire over SLI, at least according to ATI, is that it just 'works' out of the box - software does not need to have any hard-coded support for it at all, unlike SLi. PC magazine articles I have read tend to back statement this up.I'd be really interested (as would many, I am sure) to know what difference CrossFire makes to FS9/FSX performance. Just because a technology is 'supported' doesn't mean it will make any difference in performance terms I suppose.Similarly, where did you see that FSX does not support dual-core CPU processing? I have no knowledge of this one way or the other and would like to read more.Thanks,Martin
