Your ROG laptop does not already come with an SSD? Might be useful to check; you may be buying the same item twice. Also look at external GPU setups. Basically, you can buy a full-sized GPU, buy some hardware, merge the two together, and use that to power your pixel-pushing without upgrading your entire laptop. I've only known about this in passing so not sure how viable it is, but might be worth a good research for your case. IMHO, all games will benefit from a good GPU whereas only DCS really insists on 16GB RAM or more.
