Thanks, I don't do any gaming but I would like the ability for multiple monitors. This article suggest that the latest 2012 models do support 2 external displays - http://arstechnica.com/apple/2012/06/new-macbooks-can-manage...
8GB of ram + SSD will get you far!
If only it had 16GB (not available on the 13" rMBP model), it would be the perfect laptop
