I recently bought a discounted RTX 5070, but damaged my motherboard and possibly my CPU while installing it. I had to rebuild the system using older parts, and now the Ryzen 5 5500 seems to be bottlenecking the new GPU. Borderlands 4 has become extremely stuttery and nearly unplayable, even though it ran better with my previous motherboard and CPU. I'm also concerned about getting good performance in the upcoming Control game.
My current system is a B450M-A motherboard, Ryzen 5 5500, RTX 5070, and 32 GB of DDR4 memory. Would it be more cost-effective to upgrade the CPU and motherboard to a newer DDR5 platform, possibly buying a prebuilt and selling its included GPU? Or should I keep the current platform, update the BIOS, and install a faster Ryzen 5000-series CPU?

A Ryzen 7 5700X would be a solid match for the RTX 5070 without requiring a full platform replacement. Just make absolutely sure the BIOS supports it before swapping CPUs. Also, Borderlands 4 appears to be poorly optimized, so some of the stuttering may be the game itself rather than your hardware. Your motherboard’s PCIe 3.0 NVMe support is slower than PCIe 4.0, but that usually won’t make a major difference to in-game frame rates.
It may be worth checking the secondhand market for a complete AM5 or LGA1700 system without a graphics card, then comparing the total price after selling any included GPU. However, unless you find an unusually good deal, replacing only the CPU is likely the best value here. Your B450 board and 32 GB of DDR4 can remain useful for quite a while.
Before spending money, verify that the game is installed on an SSD and check whether the drive is nearly full or showing signs of wear. A five-to-seven-year-old SSD could contribute to long loading times or asset-streaming problems, although it wouldn’t normally explain a major CPU bottleneck by itself. Since the system performed better before the motherboard and CPU were replaced, check BIOS settings, memory speed, temperatures, and background processes too.
The most practical upgrade is probably staying on AM4. Check the motherboard’s CPU support list, update the BIOS, and look for a Ryzen 5 5600X, Ryzen 7 5700X, or another Ryzen 5000 chip that is reasonably priced. A 5800X3D would be excellent for gaming, but it may cost too much compared with the other options. You might also need a better cooler depending on the CPU you choose. DDR4 is still perfectly usable, especially with current DDR5 pricing.
That makes sense. I wasn’t sure whether a discounted prebuilt plus selling its included GPU would make DDR5 worthwhile, but keeping the existing DDR4 platform seems simpler.
I hadn’t considered the SSD interface. I’m using an older SSD, so I’ll check its health and performance, but it sounds like it probably isn’t the entire problem.
