In that case you may want to consider dropping down on cpu to get a better graphics card. His $850ish build will probably serve you better than going up on CPU and ram UNLESS you plan on putting funds aside for a GPU upgrade soonish.
That said, I would say an NVME drive will boost you quite a lot simply due to the read write speeds compared to a sata SSD. It will be noticeable.
Compound interest will far outweigh paying taxes now for a Roth. Especially if you also have a 401k, the taxes in retirement will be potentially large based on the growth of the fund over decades. A Roth makes it so you pay nominal taxes now for potential large tax free growth later.
The exception would be if you think your income will decrease in your later working years, in which case a traditional IRA could make more sense. That however is a unique case. Generally it’s better to take advantage of a Roth if you can for tax free gains later.
