Lol? What could make you prefer nVidia to ATI? Is it the time bomb aspect of the current chips, or their (lifelong) inferior image quality?
What time bomb????
Not really concerned about having the latest, greatest. More concerned with reliable, stable hardware and drivers. My gaming PCs (at home and with my kids and grandkids) all moved to ATI over the past year. Nvidia cards required too much power, and the DX10 drivers for our current favorite, Company of Heroes, were awful. Mostly using 4870, 3870, 2600 and 3470. Can't get the best frame rates and highest resolutions with some of those, but they all work, even with only modest CPUs and power supplies.
Additionally, on the Mac side, we are never going to get the greatest GPU so let's get one that works very well on OS X and has decent Windows performance with no hint of imminent failure. Right now that means ATI.
Cheers,
I'm not concerned about the latest and greatest, I just want a MacBook Pro to use.
