Yes it is but if you have a supported MB download virtu MVP. It will use both cards for gaming my friend uses it on his Intel. It will have a list of supported boards on there. Supp you can get 40fps more by using both
But I would keep your card since PC gaming will always be better than a console. I don't even touch mine anymore. but its your choice. Depends on if the card is even worth selling. What is it?
