Honestly for the price of both cards and a psu with enough watts to run both,You could spend the same money and get a single gpu that is faster.Gaming with two gpus can be good and bad.Not all games support it so the 2nd gpu will run at idle.And thats if it works right sometimes it can be picky and give you problems.And if it does work both cards won't run 100% either.This is why most of us preach buy the fastest single card you can afford.

thanks guys

The board supports 64GB, so 4x16GB, but you can always get double height RAM for 32GB per stick if you need more storage and hope it works. Linus talked briefly about it in one of his videos a while ago, not much though, and don't remember when.

There are four DDR4 ram slots on your MOBO assuming they are all functioning properly. This means you can have up to 64GB of RAM in the MOBO 4x16GB ram sticks. Most people will stop at 16GB so 2x8GB RAM sticks as anything more is generally overkill unless you are doing something such as using multiple virtual machines or its for a server/hardcore streaming PC.  Hope this helps
