Yep, cheapest would probably be one of the i5/6300 laptops. I've predominantly seen those in the Dell 7000 series. A decent CPU - first laptop 4-core i5 they've made - just lacks the hyperthreading of the i7.
Honestly I've been looking at the Dell Insiron i7559 for a while now, but I was just wondering if there was a GTX 965M under $1,100. The Dell is probably the king for the $800-$1000 market, because of the i7 and 4GB GTX 960M.
