I got new hardware and old hardware and it seems like dirt and collatz just depend on the gpu. My experience with poem is that the computer matters as much as the gpu. So if you are just looking for a platform that runs the gpu for projects like dirt and collatz, I would suggest going with the easiest solution. If you want something that can run more cpu projects and handle gpu projects like poem, go with the 4770. That is my . Good Luck.
