Com a saída das novas gráficas RTX seria agora uma boa oportunidade de fazer o upgrade para uma GTX 1080 Ti?
Li que para edições de video em 4K ( suaves e fluidas) seria aconselhável, no mínimo uma GTX 1060 6GB, alem dos óbvios discos SSD (que já tenho)
"
For an entry-level video editing GPU, we recommend the GTX1050 or GTX1050 Ti.
At 4K or above, a GTX 1060 6gb is a good choice. If you want to go all out, you will see more improvements from the GTX 1070 or GTC 1080.
If you're doing GPU-intensive tasks, you'll get the best performance from a GTX 1080 Ti. "
Entretanto numa leitura mais aprofundada, dá me a sensação que uma melhoria notória de performance seria no CPU (atualmente I5 3570K + Mobo Asrock Z77-Pro4) e aumento de RAM ( atualmente tenho 2x8Gb Kingston-HyperX-Savage-DDR3-2400MHz )

Once you have an OK video card, investing in greater GPU power will not significantly improve video editing performance.
A powerful video editing PC is build around a powerful CPU. Having a graphics card is also very helpful, but it is not necessary to get a powerhouse of a GPU. Make sure not to skimp on RAM, either, but 8 to 16 GB should be plenty for most projects. An SSD won’t increase raw rendering speed, but will make everything else feel faster and is a valuable addition.
