m395 vs. m395x for Pixelmator?

[musika]

I know there are a ton of threads about the GPU of the new 5K iMac, but I haven't seen any discussion that applies to my needs.

I'm a designer who uses Pixelmator a lot. Lots of layers, lots of shapes, lots of images.

I don't play any video games.

Is the m395x upgrade worth it, or no?

Thanks!
