If you'll get the I5 and make some modifications it will be great:1
1. The I5 version which is as good for gaming as the I7 version, but produces less heat. Also, if you'll end up with the Y510p again, come back to here and we'll talk about how to limit the heat a little with Nvidia Inspector and Intel XTU. It can really help
2. The GT60 isn't that great. The Sager NP8235 is better in terms of thermals + it's cheaper if you can install an OS
