Im thinking of buying MSI GT60 2OD-026US as the title says, and it's one of the recommended ones on the side. Im not familiar with MSI, but the specs are top of the line:

Screen Size 15.6 inches Screen Resolution 1920 x 1080 Max Screen Resolution 1920 x 1080 pixels Processor 3.2 GHz Intel Core i7-4700MQ RAM 16 GB DDR3 Memory Speed 1600 MHz Hard Drive 1024 GB SATA Graphics Coprocessor NVIDIA Geforce GTX780M Graphics Card Ram Size 4000 MB Wireless Type 802.11bgn Number of USB 2.0 Ports 2 Number of USB 3.0 Ports 3 Computer Memory Type DDR3 SDRAM Flash Memory Size 128 Hard Drive Interface Serial ATA-600 Hard Drive Rotational Speed 5400 RPM Optical Drive Type BD Combo

My main use will be video editing, graphic design, and of course gaming. Any tips or advice before I commit? And will this setup allow for real-time view of video edits?
