The dead pixel policy only applies to the Acer. Sager has the 30 day money back no questions asked which Acer does not have. We've tried to get a no dead pixel policy with Sager, but the price hike would probably push most people away from being able to buy.
As far as which is best for gaming, I personally still choose the Sager 8790 mainly because of this higher FPS. The exhaust vent, AC power plug, and Audio jacks are on the right hand side of the Acer can bother right hand external mouse gamers but I wouldn't consider that point break. Both LCDs are great, but the Acer has more of a noticable uneven brightness (in streaks) which you can kind of see in the attached pic. All LCDs have this to some degree.
No, it does not come with a case standard and I would consider that pretty common. Many of the big names out there don't come standard with a carrying case.
