For a gaming computer, don't ever go near any laptops, they are too weak against PCs in comparison their prices, because their goal is being portable, not gaming!! after all, laptop's lifetime is much less than PCs.
For a gaming computer under $1500, i suggest you consider the graphic card first, pick something good, around 500$, CPU shouldn't be so powerful in gaming, something inexpensive but new! other stuffs are same as cpu, no need, you can skip SSDs storage if you were planing to. Motherboard, ASUS 8 series could be nice.
The 290 is a great GPU but if you're willing to sacrifice the SSD and get a 780 Ti you can, but it is actually not that wise as the 290 is great and you can still overclock it. This is the non-reference design btw.
