I need some ideas from you guys.

Im using Toshiba P50

i7-4700qm, 16gb ram, 256ssd. 15.6" full hd screen, dvdrw.

have a chance to upgrade to Asus G750JX; swap plus cash (RM1500).

1.) Keep P50
lightweight, good for normal gaming (dota2), cant handle 3D games. Maybe FIFA and car racing game is fine for me. Saving $$ for future laptop upgrade.

2.) Upgrade
One of the best laptop with bluray writer (I might need bluray writer to back up all my important files rather than store these file on USB hdd. Like to have bigger screen.

Note: I dont normally bring laptop around. If I do, G750JX would be a bit bulky for travel.
