i7-4700MQ
GTX 860M GDDR5 2.0gb (This one has the newest kepler core this GPU is better than a 765m and a bit slower than 770m)
$988.43 if you pay in cash
I was also set on the y510p was gonna get the 755m sli option started researching about it and found out that some of the unit runs relatively hot especially the second GPU which is in the ultrabay
