The problem with the 4000 is, that it is not going to render faster. It also depends how fast the cpu is. Different speeds for the 4000 is depended on the cpu model. Is Tis conperable with the geforce 3300m series. I had a 940m series and poser did not render fast.

I would go for a Gigabyte GeForce GTX 1660 Gaming OC 6G, that one is around 300 bucks
