Urm, Ani.. I will be honest.. just before the beginning of this month, I had a crappy Lenovo Y570A with the 555m gpu. It sucked, I hated it and just as this month began its hard drive gave up. I looked around the internet for good laptops, I came to one conclusion.. Laptops are inferior to Desktop gaming rigs, IF you can.. I suggest you go for a gaming rig not a laptop because they are a lot more cheaper in the long run.
My current desktop specs: ( I call it Xerses)
Asus Sabertooth Z87 TUF Edition motherboard.
Intel Core I7 4790k processor running at 4.0ghz
Asus GeForce GTX 680 2gb (To be replaced with the gaming edition MSi GeForce GTX 980Ti, not sure if its 4 gigs or 6 gigs)
Corsair DDR3 Vengeance 16 gigs @ 2400mhz
Corsair power supply Rm850 watts
Samsung SSD 850 Evo 500gb
NZXT Case H440 (Red and black)
Corsair H90 cpu cooler
LG LED monitor 24"
Windows 8.1 pro 64 bit
Logitech keyboard G105
The entire thing I am assuming would come to around 2k USD.
You can build a decent rig at 1k but if you can, go for a desktop instead of a laptop. I will post you some links:
