Opinions on this laptop please!

My 3 year old Toshiba Satellite Core 2 Duo is getting a bit long in the tooth. Looking forward to USB 3.0 among other things for faster transfering. I am not familiar with MSI but the specs for the price are hard to ignore. It's billed as a gaming laptop. I process thousands of RAW files and short videos from a Nikon D3s & D800. Cheers!
