Had my X7 for two months now and still think its the best Windows laptop I've had. I use it every day alongside my work laptop, I don't have room for a full size PC and this is a very close 2nd best due to the screen (refresh + G-Sync) and SLI GPU's. Obviously can't compete with a 980Ti SLI rig but that's overkill for my needs at 1920x1080.
I've also added 2 x 1TB SSD's and every game I have runs on max settings, from BF Hardline to Star Wars Beta.
Will definitely look at this model again when my next upgrade itch kicks in (about 12 months), possibly sooner if the following happen:
1. 4K IPS screen.
2. Next gen GeForce GPU's in SLI.
3. M.2 SSD drives (preferably 4, don't worry about the 3.5" bay).
4. Mechanical keyboard..?
Form factor is great, looks fantastic and I can't see myself getting another full form factor gaming PC again really.
