ohh and as an added bonus, it should be more battery friendly since it's on 40nm instead of the 285m 55nm
So basically it is better than even SLI GTX 285 in some casses, as I see from bench Marks, and uses less power, in addition to the price it is cheaper. Anything to add, I am going with 5870 that is for sure. How about reliability durability?
That is a very good choice. As for durability and reliability- it uses less power and generally produces less heat- always a good thing for longevity. It's a high end card (even the mobility version) and should last you well and be very reliable.
