Hello guys, I have a quick question...is the alienware laptop shown at this link (http://www.dell.com/en-us/shop/productdetails/alienware-17-laptop/dkcwkblg44s) the Alienware r4 17? I honestly have no clue, and also, what is better? A Acer Predator 17 with 16 gb ddr4 ram, gtx 1060 and 256 ssd with 1tb hard drive, or the alienware?
