The nVidia RTX 4060Ti  @ 244mm long should fit in your rig nicely.
I have an XPS 8930, i9-9900K CPU, 3.6 GHz, 32 RAM. Current video card is an Nvidia GeForce RTX 2070. I want to upgrade the video card to see if After Effects and Premier Pro will run faster and smoother and not crash as often. Wondering what the best possible graphics card is for this system. Thank you.
XPS 8930, upgrade from GeForce RTX 2070?
