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.
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.
What is your budget? That looks good, I would just add a M.2 NVME SSD and then later when you can upgrade the graphics card. His September video has good recommendations for those. Also looks like the 7800x3d is sold out most places but if there is a Best Buy near you they may have it in stock. Good luck!
Check this out to compare but I’d up the cpu to a x3D at least

Bad news: nothing is really worth salvaging except maybe the HDD as a spare data drive but SSDs are cheap enough to warrant the upgrade and the TV (though a monitor would be better)
Good news: PCs aren’t that expensive right now and you can make a good build for even a cheaper budget. Check out this channel for more info https://youtube.com/playlist?list=PL30pfjH1BVN908ZV3QJRAakq-4mANnInm&si=Wth4bAzl_3uA5Mk-
Check out this channel. He has a lot of good information and also full builds that will fit almost any reasonable budget. He also gives upgrade paths and where you can improve the builds. https://youtube.com/@PCBuilderChannel?si=LFv8SrBzojZIgFAD
The internet is getting shittier because the services themselves are getting worse through consolidation and acquisitions instead of improving products so we need to make laws that protect users and giving them means of keeping those services accountable.
