A couple of months ago I picked up an ASUS G75VW, it's an older gen laptop with a 3rd generation I7. Below are the specifications for it:
Brand/Model: ASUS Rog G75V Display: 17.3" Full HD CPU: Intel Core Intel i7- 3630QM upto 3.40GHz GPU: NVIDIA GeForce GTX 660M Storage: 120SSD for fast start-up and 750GB HDD for storage RAM: 12GB
Plans are already forming as to what to upgrade, the CPU is socketed and the GPU is a MXM standard so there are some options for it.
RAM of course and an external clean-up and afew other internal mods I have been thinking about doing to it.
