Only showing one graphics card?

[NikkiJayne]

Hi all,
my new retina Macbook Pro has just been delivered (my previous one was stolen). I opted for the more expensive 15 inch version with 2 graphics cards - however, under 'about my Mac' it's only showing the Intel Iris one!

Have they sent me the wrong model?!

EDIT: Never mind, I found it under System Report!

Open up the system report (About this Mac>More info>System Report)

Do you see one or two GPUs?
