Hello, I am getting a 4K monitor, but I run an old dinosaur of a PC running VP14. It could barely playback 4K and renders relatively slow. I will upgrade to a better workstation, but I want to get a graphics card I will eventually move to a newer PC. I was looking at the Quadro P400 or the GTX 1050 Ti, but my PC has PCIe 2.0 and these cards have 3.0. I will eventually upgrade to Vegas 15 and to my knowledge these cards will benefit from the new encoder. Would the 2.0 bottleneck with these cards? Would I see any benefit of playback or rendering with these cards? Lastly, would these cards on my PC output 4K? My current editing style is stop-and-go where I pause a frame and grade with it paused at the highest preview quality. I will find specs ASAP, but the model is a Dell T5500 and one processor is missing. Sorry for the lack of info. At work right now.
