I recently bought an RTX 5070, but the rest of my system is fairly old: an Intel i5-9400F, MSI H310M PRO-VDH motherboard, 16GB of RAM, a 750W power supply, and a 1.25TB 2.5-inch SSD. I usually play a wide variety of games at reasonable settings—not necessarily Ultra or 120 FPS—and I'm particularly interested in playing War Dogs. I don't have a fixed budget yet, so I'm planning to save up for the parts I need. What CPU, motherboard, and RAM combination would pair well with the RTX 5070 without wasting its performance?

Your i5-9400F is old enough that upgrading the platform makes sense, especially since you’re moving from a GTX 1070 to an RTX 5070. Don’t just replace the CPU and motherboard—plan on replacing the 16GB of older RAM with a 32GB DDR5 kit as well. A B650 or B850 board with a Ryzen 7600X3D is a sensible starting point, and you can move to a faster AM5 processor later if needed. The SSD can remain for now, although an NVMe SSD would improve loading times.
There isn’t one universal setup that has no bottleneck. The result depends on the games, resolution, graphics settings, and frame-rate target. At 1440p in demanding AAA games, the RTX 5070 will often be the limiting part, which is perfectly normal. A Ryzen 5 7600X3D or Ryzen 7 7800X3D would be more than capable; you don’t need the most expensive processor just to make the card useful.
The usual recommendation would be an AM5 platform with a Ryzen 5 7600X3D or Ryzen 7 7800X3D. Pair it with a decent B650 motherboard and 32GB of DDR5-6000 memory. The 7600X3D is generally the better value option, while the 7800X3D gives you more headroom for CPU-heavy games and future upgrades. Your 750W power supply should be sufficient if it’s a good-quality unit and has the correct GPU power connectors.
I misunderstood bottlenecking and thought it meant the whole system would be held back. I mostly want to avoid my old CPU causing serious performance problems.
