Is a GPU upgrade worth it?

[JonFar]

Hey guys.

I'm thinking about upgrading my GPU (Nvidia 750ti 2gb) to a Nvidia 1080 8gb.

I use sketchup 2018 with Vray, and have an i7 6700k with 32gb DDR4 and 2 fast SSDs.

So, for sketchup and rendering I dont really need a GPU upgrade, but I want to try Lumion for the animations, and a 750ti won't cut it...

My question is:
Will I notice a viewport improvement in sketchup with that GPU upgrade? And also a will my CPU+GPU rendering times benefit from that?

Or is that upgrade (750ti to 1080) only worth it for other 3D software, like Lumion?

you'll surely see improvements in SU too, at least w/ high polycount (aka big) models.

a GTX 1060 6GB might do it already, the GTX 1070 very likely:

thats good to know, because my 100+ mb files lag a bit
but I always thought that it was "normal" and that Sketchup was mostly CPU/RAM intensive, so I kept my old GPU

definitely going for that upgrade then, thanks for the reply

Do you have room for 2 GPUs? If you do then I would go with a EVGA GeForce GTX 1080 Ti FTW3 GAMING, 11GB GDDR5X, made to run in dual mode later on (when you need another upgrade

SU is CPU intensive (single-thread performance ), nevertheless for a balanced system an appropriate GPU (as well as enough RAM) is of course required too. Don't invest to much in a GPU, at least for sole SU modeling purposes, otherwise you will be disappointed.
