I have many, many cards of all flavors, for work it's the best and they cost an arm and a leg, 5 large each and yes, the ARE worth every penny.
gaming cards, it all depends, I find that the games I enjoy the most and that give me the break I need can be played with onboard graphics, but playing the same game on a pair of 980Ti cards just gives me a grin.
nobody can tell you what the perfect card for you is, but a pair of 760 strikers.............................................well that's hard to beat in my book.
