I would be against the 4k GS60 ghost pro. It has the samsung tn panel which has the bad color accuracy like the ones in the lenovo y50. It also locked into a 48hz refresh.
Please ignore. I didn't read the cd/dvd drive lol ummm.. i think the gigabyte p35x v4 has all the specs you're looking for. I know a laptop reseller who sell that laptop ,brand new, for super cheap. PM me.
