New Laptop For University Studies

I'm in need of a new laptop, preferably a gaming laptop. I'm a first year student at University Malaysia of Computer Science and Engineering, and is taking Diploma in Computer Science (Game Development). My current laptop is over 5 years, and is gradually degrading, some basic programs has stopped working, my hard disk is dying, and there are currently 8 bad sectors. Apparently, I need a new laptop with better specs for my future projects as a game developer, one that can install a lot of softwares and programs for my studies.
