The HP Pavillion 15 ab221TX is one of the best laptops one can get in medium range premium laptops.
It comes with i5 processor and 8 gb Ram and 1TB harddisk and a good deal at a range between 50_ 55 k .
It even comes with BANG AND OLUFSEN speaker system.
However you can also opt for au006 which has 4gb of NVIDIA graphics.( smooth experience for gamers)
To summarize
AU111: 53k ( 2gb NVIDIA)
AU006: 55k( 4GB NVIDIA)
BE002tx: 48k( 2gb AMD RADEON)
All in all I can say I have these experiences from past six months go for it without any problem.
