NVIDIA P4000 or P5000

Hi there,

running MC 2018.11 on a Dell T7610 with windows 10, 128Gb ram, etc.

currently using a NVIDIA K4000 but it's time to upgrade.

Have been looking at the P4000 but wondering if the P5000 might be a better value even though even though it's almost twice the price.

any advice welcome

thanks
