I'm planning a work and gaming upgrade with a budget of about $2,000. My current system uses a Threadripper 2950X, an RTX 4090, and 128GB of DDR4 memory. I use it for 3D visualization, modeling, and Photoshop, where large projects can consume a lot of RAM, and I also game at 4K and above. DDR5 prices make a full platform change less appealing, so I'm considering a DDR4-compatible 14th-generation Intel system or possibly staying with an AMD DDR4 platform. Would either option be a worthwhile upgrade, and how realistic is it to keep using all 128GB of memory?

Be careful with memory support on a 14th-generation system. The official limits and real-world stability depend on the motherboard, DIMM configuration, and memory modules. Four 32GB DDR4 sticks may work, but you should choose a board with strong memory support and be prepared to run them at standard speeds.
A complete DDR5 rebuild would give you a newer platform and better memory bandwidth, but it may force you to compromise on capacity or spend more than planned. Unless your workloads clearly benefit from DDR5 bandwidth, keeping 128GB of DDR4 and choosing a stable, well-supported motherboard is probably the more practical route.
First, confirm how much memory your actual projects need. A 128GB DDR5 kit plus a new motherboard would take a significant chunk of a $2,000 budget, so keeping your existing DDR4 is understandable. A DDR4-compatible 14th-generation Intel board can support 128GB, but four populated DIMM slots may require conservative JEDEC settings rather than high overclocks.
The 128GB is intentional rather than just a gaming requirement. Large visualizations and Photoshop projects can use a lot of it, so I’d prefer not to reduce capacity.
Since the 2950X uses a Threadripper platform, moving to a newer Threadripper processor may require a motherboard change and could quickly consume the budget. If your applications benefit from high core counts, compare a platform upgrade against simply replacing the CPU and board while retaining DDR4. For gaming at 4K, the RTX 4090 is already doing most of the work, so the upgrade is mainly about productivity performance and CPU-limited games.
It may work fine, but expecting the advertised memory overclock speeds with 128GB installed is less realistic than running at JEDEC settings.
