For stuff like Lightroom and Photoshop, the integrated HD Graphics 4600 should do you fine. For bit more intensive stuff like video editing however, my experience is that a dedicated graphics card can indeed do you well. In this case though, a 730 wouldn't make much difference however. Rather I'd probably stick in something like a GTX 750 for CUDA (alternatively a R7 260/260X for OpenCL) which might make Vegas or any other video editing software run a little snappier.
Quicksync is fine for general use, but the way it works is that it actually trades a little bit of video quality for much more speed, so the resulting file you render out might not look as good and detailed as it should compared with the methods such as CPU-processing (AKA no acceleration, slowest) or CUDA / OpenCL (slower than Quicksync but quality shouldn't be affected, also a dedicated graphics card).
It all comes down to how much video you're planning to edit generally and also if you play any games at all. Aforementioned dedicated cards will be miles better than the intergrated HD Graphics 4600 for pretty much any game.
