I'm thinking about replacing my five year-old Acer laptop and wondered what other people use for mobile editing?

I have several customers that require me to edit photos and video on site, and whilst my current PC laptop (i7 4702MQ, 16GB, GTX760M, SSD) can cope with HD editing it starts to struggle with extra layers of text and effects applied and the preview is rough.

Dell seem to do some high spec laptops, though not cheap.

I'm using Vegas Pro 15 at the moment and in the UK.
