I currently have an RTX 3060 and am planning to upgrade to an RTX 5070 Ti. I do 3D work and would like to use both graphics cards in the same PC for rendering. My motherboard is an MSI PRO Z690-P. Is this setup practical, and are there any power, PCIe, software, or cooling limitations I should consider?

Yes, you can run both cards together for many productivity and rendering workloads, provided your power supply has enough capacity, your case has suitable airflow, and your software supports multiple GPUs. The cards may run hot when installed close together, so check the slot spacing and cooling carefully.
This combination is much more useful for 3D rendering and other GPU compute tasks than for gaming. Supported applications may be able to split the workload between both GPUs, but they generally will not merge the cards into one larger pool of video memory. Games usually use only one GPU, so don't expect the RTX 3060 and RTX 5070 Ti to combine their performance.
A second card can sometimes still be useful for specific tasks such as PhysX or background workloads, but compatibility depends on the game or application. Before installing everything, check the total power draw, the connectors required by the 5070 Ti, available clearance, and whether the lower slot leaves enough room for the 3060's cooler.
