Hi folks, I desperately need your help. I purchased a Sapphire 4870 HD TOXIC a week ago thinking it would be relatively simple to flash this 4870 card. The more I delved in it became apparent this was not the case. Can some direct me to a ROM which is compatible with this card? I have googled, searched and even Bing'd to find an answer but nothing is crystal clear. The card obviously works under Boot Camp, but I just need it work work under OS X and I'll be one happy photographer!! Cheers.
