A new computer would be much faster - for example a Lenovo THINKSTATION P350 TOWER I7-11700K 16GB 512GB SSD W10P - 30E3003KUS - about $1,400.00 - has a CPU Benchmark of 24,727 vs. your CPU Benchmark of 9,662 (2.5 times faster). Or, a Lenovo THINKSTATION P620 RYZEN 3945WX 16GB 512GB SSD W10P - 30E00006US - about $2,400.00 - has a CPU Benchmark of 33,441 (3.5 times faster). But you would need to add memory to get it up to at least 32 GB, a video card (at least $300.00, although your video card has good specs) and two storage drives (4TB SSD's would be at least $350.00 each), so it's an expensive investment. Your computer was top-of-the-line when you got it and you got 5 years out of it, so it was a good investment. And, a new machine with the above specs would also be top of the line, so you should get a long useful life from it as well.
