Thanks for the info I appreciate the info... realizing I don't have as a good a grasp as I thought I did on how osx86 is working under the hood - time to start reading up again. One thing did come to mind though. I know with my current 8800gt I had to wind up disabling a few kexts (AppleUpstreamUserClientDisabler, IntelCPUPMDisabler, etc.) in order to stop some random momentary lockups I was experiencing... and then I later learned that a few guys actually resolved the issue permanently by simply flashing their cards with the mac firmware. This is more what I meant when I said "preventing compatibility issues". I wonder if there are any similar issues w/ the GTX 285? I'll probably just hold off for now and then if issues arise consider doing the flash then. Thanks to both you and The Rominator for the help.
