I recently upgraded from a GTX 1660 to a PowerColor RX 9070 GRE 12GB and replaced my old 650W power supply with a 750W Gold unit. The GPU made a huge difference in native 1440p gaming, but I'm seeing CPU usage hit 100% while GPU usage sometimes sits around 89%. In Black Ops 7 multiplayer at ultra settings with no upscaling or frame generation, I'm getting roughly 90–110 FPS on most maps, 120–130 on lighter maps, and 85–90 on the heaviest ones. Frame generation pushes the counter above 170 FPS, but I'm mainly interested in real rendered performance.
The rest of the system is a 2020 build with an i5-9600K, H370 motherboard, 16GB of DDR4-3200 running at 2666, a SATA SSD, and a 1440p 165Hz monitor. I'd like around 140 FPS or better in multiplayer and 120–130 FPS in Warzone at ultra settings, without upgrading the monitor or chasing 200 FPS.
I'm considering replacing the platform with one of several current CPU, motherboard, and memory bundles. The options range from a budget 7500X3D or 7600X3D bundle to more expensive 7800X3D, 9800X3D, Ryzen 9700X, and Intel Core Ultra bundles. The cheaper packages include 16GB of DDR5, while the more expensive ones include 32GB. A 32GB DDR5-6000 kit is unusually expensive on its own right now.
Is the 9600K holding the 9070 GRE back enough to justify a complete platform upgrade? If so, which bundle offers the best balance for a 1440p/165Hz gaming system? I'm currently leaning toward the 7800X3D bundle. I can also exchange the GRE for a 9070 XT for about $720, but I'm unsure whether that extra GPU performance would be worthwhile with my current monitor.

The 9070 XT is substantially faster than the GRE, so pairing it with a strong gaming CPU would produce the highest numbers. That said, the GRE is already a sensible match for 1440p, especially if your target is around 120–165 FPS rather than maximum benchmark performance. I’d fix the 9600K platform first and see where the GRE lands before paying the premium for the XT.
Among the AMD choices, a 32GB bundle is preferable for a new gaming build, but the 7800X3D is probably more CPU than the GRE requires at 1440p. A less expensive 7600X3D or similar modern gaming chip could deliver most of the practical benefit, while the 9800X3D-tier options make more sense if you plan to keep the platform through another GPU upgrade.
The 9600K is becoming a real limitation in newer multiplayer games. Six cores without additional threads can produce exactly the kind of situation you’re seeing: the CPU is maxed out, frame rates vary heavily by map, and the GPU isn’t consistently being fed enough work. A modern platform should improve both average FPS and frame-time consistency.
For value, the Core Ultra 5 250K bundle is worth a serious look. It should pair well with the 9070 GRE, and the bundle pricing makes the processor and board unusually attractive. Since you don’t upgrade CPUs every generation, the platform’s long-term upgrade path may matter less than getting a strong deal now. The 9070 GRE should also be enough for a 1440p/165Hz display once the CPU limitation is reduced.
I’m not trying to exceed what the monitor can show; I mainly want a balanced system that can make the most of 1440p and 165Hz without spending heavily for performance I won’t see.
That’s my concern with the more expensive options: I want enough CPU headroom to remove the current bottleneck, but I don’t want to pay for a setup that is mostly wasted behind the GRE and this monitor.
