So I'm looking to getting a new Window's laptop to take to work as well as play games on when I'm away from my desktop. Right now I'm looking into the Lenovo Y500 or Y510p. They have the 510 for 950-1100 and I'm leaning towards that but I wanted to know if there was a significant difference with the two GTX750 dual graphics and just one GTX 750. Also would it be worth the downgrade from Haswell to Ivy bridge i7 to get the dual graphics card for 800 bucks instead of 1100. The sale from Lenovo only lasts until Sept 4, I'm not familiar with how Lenovo runs sales but I'm going to take this as something that won't happen for a bit longer.
