I think at this point AMD has no choice but to "game works" their titles. AMD has tried for how long to be a good corporate citizen and push open standards. Where did it get them?
Not really the same, Nvidia already had fundamental GPU tech AMD didn't. AMD gets a whole lot of crap for over paying for ATI, yes they did but long term it was a great acquisition. IIRC Intel paid more for McAfee than AMD did for ATI.
For reference I tested 3 new Sony CMOS batteries the average was 3.254 volts. As for load from the motherboard it is nearly zero that's why a CMOS battery can last 15 years.
