Here is a link with 12.8
, Imagine whats going to happen with AMD CATA 12.11 beta 7?http://pctuning.tyden.cz/hardware/notebooky-pda/25335-test-mobilnich-grafik-gtx-680m-sli-vs-hd-7970m-cf?start=5
The nVidia GTX680M gets throughly stomped by the HD7970M and 7970M is cheaper by few $$$ hundred Dollars
I have to say that the Enduro
is not as good as Optimus
, but its getting there and matters if you SLI or XFIRE, but even so, in dual cards the AMD is faster but the support for Optimus is stronger bcoz its been around for much longer than Enduro.
