I built my current gaming PC around 2016 and have only upgraded the RAM and added another SSD since then. I'd like to reuse anything that still makes sense, but I'm mainly looking to replace the CPU and GPU for smoother performance in newer games such as Clair Obscur and Path of Exile 2. I'd also like the option to move to 4K gaming later.
My current parts are:
- Intel Core i7-6700K
- 2x DDR4-2133 memory sticks
- NVIDIA GeForce GTX 1070 8GB
- MSI Z170-A PRO motherboard
- EVGA SuperNOVA 650 GQ, 650W, 80+ Gold power supply
- 1TB SSD
- 500GB SSD
- 1TB hard drive
I was initially considering a Ryzen 7 9800X3D with a GeForce RTX 5070 Ti, but I'm unsure what else would need to be replaced. Can DDR4 be reused with a newer motherboard, or would I need DDR5? Is a new power supply necessary? I'm in Germany and want to spend as little as possible while still getting a worthwhile upgrade. Would an older AM4 platform or used components offer better value than building around AM5, or should I wait for prices to settle?

Realistically, the case and storage drives are probably the easiest parts to reuse. Your planned 9800X3D requires AM5 and DDR5, so your existing memory cannot come along. For gaming value, a Ryzen 7 7800X3D paired with a Radeon RX 9070 XT may deliver similar practical performance for less money than the high-end NVIDIA option, especially if ray tracing and specific NVIDIA features aren’t priorities.
A motherboard cannot use both DDR4 and DDR5, so a Ryzen 7 9800X3D build would require an AM5 motherboard and DDR5 memory. That makes it a much more expensive platform upgrade. If keeping costs down is the priority, a used AM4 system can still offer excellent gaming value. Something based on a B450 or B550 board with a Ryzen 7 5800X, 5500X3D, or similar chip could let you reuse less expensive DDR4 memory. For the graphics card, look at the used market for cards such as the RTX 3070 or newer equivalents, depending on local German pricing.
A full AM5 build around the 9800X3D and RTX 5070 Ti can easily reach roughly €2,000 or more once the motherboard, DDR5 memory, cooling, and other required parts are included. It’s a powerful option, but it doesn’t match a minimum-cost upgrade very well. Your SSDs and possibly your case can likely be carried over, while the motherboard, CPU, memory, and probably the PSU would need attention. An AM4 upgrade or carefully chosen used parts would reduce the cost substantially.
I upgraded from a very similar i7-6700K and GTX 1070 setup. Moving to an RTX 3070 improved graphics quality a lot, but the old processor still caused stuttering. Switching to a B550 motherboard and Ryzen 7 5800X made the system feel much smoother. If you want to minimize spending, an AM4 build with a used or discounted processor and a used RTX 3080-class card could be a strong option. I’d also seriously consider replacing the power supply, particularly if you choose a newer, more power-hungry graphics card.
I’ll look more closely at older hardware and used parts. Given current prices, that may be a better route than jumping straight into a completely new platform.
I hadn’t realized the newer Ryzen chips required DDR5. The alternative platform and graphics card suggestions are helpful, since I’d definitely prefer not to spend more than necessary.
