I'm not very familiar with PC hardware and would appreciate advice on how to spend roughly $300–400. My current computer is a Dell Precision Tower 3420 with an Intel Core i5-6500, 8 GB of DDR4 memory, Intel HD Graphics 530, a 224 GB SSD, and Windows 11. I mainly use it for work and scientific or technical applications rather than gaming. My typical workload includes many browser tabs, PDFs, Word, Excel, Origin, MATLAB, Python/Jupyter, ImageJ, XRD analysis software, and simulation programs. CPU performance and memory capacity matter more to me than graphics performance. I was considering upgrading to 32 GB of RAM, an i7-6700, a low-power graphics card such as a Quadro P1000, and a 1 TB NVMe SSD. However, I'm unsure whether those upgrades would be worthwhile on such an old platform. Would it be better to upgrade this workstation, or save the money for a newer desktop or mini PC?

The i7-6700 and Quadro P1000 would be improvements, but they’re still older parts and probably won’t transform the system. The Precision 3420 also has limited upgrade potential, so I wouldn’t put $300–400 into several expensive upgrades unless you can buy the parts very cheaply. At minimum, add more RAM, since 8 GB is likely the biggest problem for your multitasking. If possible, increase the budget to around $500–600 and look for a newer mini PC or refurbished business desktop with a much newer CPU and 16–32 GB of RAM.
You probably don’t need a Quadro unless one of your applications specifically requires certified professional graphics drivers or GPU acceleration. For your described workload, prioritize a newer CPU, at least 16 GB of RAM—preferably 32 GB—and a 1 TB SSD. If the current machine is otherwise stable, adding RAM and a larger SSD now could keep it usable while you save for a complete replacement.
So it sounds like the graphics card should be a lower priority, and I should focus on memory and CPU performance when comparing newer systems.
If you buy new, $300–400 is a difficult budget for a meaningful upgrade. A newer mini PC with something like a Ryzen 7 7735HS, 24–32 GB of RAM, and a 1 TB SSD could be a much better fit than an i7-6700 system. Its integrated graphics should be sufficient for normal display work and many technical applications, while the newer CPU would handle multitasking and simulations far better. The main thing to check is whether the software you use benefits from a dedicated GPU or specific graphics features.
That confirms what I was worried about. What processor, memory capacity, and general specifications would you target for my workload? The current computer still works, but it’s beginning to feel limited.
