I will mainly use this for gaming and some school. I am edging towards the GX60 because I customized it on xoticpc. I have 16GB RAM, 1 TB + 750GB. And for the lenovo I have only 16GB RAM upgraded. I have heard that the GX60's CPU bottlenecks the computer. But the Y510 has dual Nvidia Geforce 750M. I know that the AMD 8970M by itself beats the 750m SLI. But with the CPU bottlenecking affect it a lot? Which should I get and why?
