Vista runs my stuff, everything. It feels fast.
It doesnt **** up when i change hardware (not even the mainboard).
RAM was never an issue here, even when i only had 2gb. HDDs are big enough as well.
And most important:
With any other OS the max dx version is 9. This means very slow and z-fighting
plagued gsdx which in turn make pcsx2 unusuable (at least for the games i play).
No amount of rambling will make things better, we need to live with microsofts
decisions, or be left out of new technology. (Hey, nice dx10 graphic card there on your XP machine

)
