I have a dying 8800GT and am looking to upgrade it. I am considering putting in a PC 6870 considering the success people are having with them under Lion (no/minimal patching, flashing etc). My summary of issues with a stock PC 6870 from browsing this and other forums would be as follows: 1) No boot screen, requiring selecting boot camp drive from OS X rather than holding down option key. The other issue I have is that since my SSD is in the ODD bay, it doesn't show as a bootable OS X partition under bootcamp (PITA). 2) Issues with DVD player and steam, most of which solveable with the aty_init patch on groths.org 3) Unknown problems in the future when Lion is updated, Steam is updated etc. 1) and 2) are absolutely fine for me, the (relatively) technically proficient user, but an issue for others with far less tech knowledge, tolerance of bugs and ability to troubleshoot. Explanation: I share the system with my father, he uses it for its photo and video editing horsepower and is nervous about the addition of a non-Apple supported graphics solution. I also take advantage of it for these reasons but would prefer the 6870 for boot camp gaming. Simply put: am I setting myself up for a series of headaches in the future by going for the 6870 over the 5770? Or will careful patching and care over system update installations see me through?
