Trying to buy a budget computer for Premiere Pro

Unfortunately, I cannot recommend either one of those configurations for the following reasons:

1) Both systems use slow, mechanically spinning hard drives and no SSDs (which are far faster than even the fastest spinning hard drive).

2) The first system uses a very outdated GPU with abysmally slow graphics memory - combining for a GPU performance that's actually slower than the integrated Intel HD Graphics 630 that's on that i7-7700 CPU, even after accounting for the differences in performance between Premiere's CUDA renderer and its OpenCL counterpart. In fact, there have been two versions of that really lousy DDR3 version of that GT 730 - and you might end up with a really crummy one that's based on a GPU that's now more than seven years old (with only 96 CUDA cores)!

3) The second system uses a now outdated GPU that was fairly reasonable when it was first introduced back in 2014, but now doesn't support some of the more modern features that Adobe software is now beginning to make some use of.

4) Both systems have CPUs that have only four physical cores. What's worse, you chose quad-core CPUs that are still relatively expensive compared to other alternative CPUs and platforms that have more CPU cores and/or deliver superior performance-per-dollar.

I will leave it up to others what hardware is suggested since I'm on a smartphone on the road.

Oh, by the way, since you're considering a prebuilt PC for such a low price rather than a build-it-yourself PC or a custom-built one, you're pretty much stuck between a rock and a hard place at that price point: You either get a system with a substandard-performing CPU or a system that's lopsided in its CPU/GPU balance (a decent CPU but a woefully inadequate GPU).

With that kind of budget for hardware, I would consider using Premiere Elements rather than Premiere Pro.
