My current PC has an NVIDIA GeForce RTX 3080, AMD Ryzen 7 3800X, Corsair RM850x PSU, ASUS TUF GAMING X570-PLUS motherboard, and 32GB of Kingston Fury Renegade DDR4-3600 CL16 memory. I use it for Unreal Engine and Unity development, gaming, coding, occasional Blender work, and some deep-learning training. My games are demanding but not always played at the highest settings, with titles such as Jedi Survivor, Marvel's Spider-Man, Sparking Zero, and Persona.
The RTX 3080 has been heavily used since 2021. Despite regularly cleaning the PC, the card overheated internally and suffered physical damage, including deformed components and failed solder joints. A repair shop said repasting would not realistically save it, so I need a replacement.
I would like a reliable, reasonably priced GPU that gives me good performance and longevity. Because of local pricing, I may also need to replace the CPU, motherboard, and possibly add more RAM. My budget is approximately $2,500, with some flexibility for a clearly worthwhile upgrade. I found a local bundle consisting of an RTX 5070 Ti 16GB, Ryzen 7 5800X3D, and 32GB of DDR4-3600 memory for about $2,500. Is that a sensible purchase, or would it be better to move to AM5 with a newer CPU and motherboard?

With that budget, I would seriously consider replacing the whole platform instead of investing in AM4 again. A modern AM5 system with a Ryzen 7 7800X3D or a newer equivalent, a suitable motherboard, and a Radeon RX 9070 XT or similar GPU could offer a better upgrade path and strong gaming performance. The best choice depends heavily on your local prices, though. If your development or AI software depends on CUDA, NVIDIA may still be the safer GPU choice even if the Radeon card offers good value in games.
Your workloads make VRAM important, especially Unreal projects, Blender scenes, and machine-learning tasks. I would focus on cards with at least 16GB of VRAM, such as the RTX 5070 Ti or higher-tier options if prices allow. The 32GB of system RAM is usable for now, but 64GB would be a worthwhile later upgrade for development and 3D work. Before buying, compare the local price of a complete AM5 build against the bundle rather than assuming the older 5800X3D platform is automatically a bargain.
A $2,500 budget can sometimes cover an entirely new computer, especially if you can sell the working parts from the old system. I would price out a complete AM5 build with 32GB or 64GB of DDR5, then compare its actual GPU performance and VRAM against the local 5070 Ti bundle. Avoid adding extra DDR4 sticks just to increase capacity unless the kits are matched; replacing the memory with a proper 2x32GB kit is usually cleaner and more reliable.
The 5800X3D is still a capable gaming processor, but buying it now keeps you on the AM4 platform and leaves little room for a future CPU upgrade. If the price difference is manageable, AM5 is the more sensible long-term foundation. That said, local hardware prices matter more than international recommendations: if an AM5 setup would force you into a much weaker GPU, the 5070 Ti bundle may provide the better overall result. Keep the RM850x if it is healthy and has the proper cables, since it should be adequate for a 5070 Ti-class card.
The 3080 was inspected by a repair shop, and they said repasting would not solve the problem. The internal damage is severe enough that any repair would probably be temporary, so I am treating it as a total loss.
