I'm planning an AM5 PC mainly for 1440p gaming, streaming content, and heavy multitasking. I often keep dozens of windows and a very large number of browser tabs open, so I want a system that will stay capable for several years. My current parts list includes a Ryzen 9 9900X3D, a 360 mm Montech AIO, a Gigabyte B850M motherboard, 32 GB of DDR5-6000 CL28 memory, an existing 1 TB NVMe SSD and 1 TB hard drive, a new 4 TB NVMe SSD, an RX 7900 XT, an Lian Li O11 Vision-M case, and an 850 W Platinum power supply. I can purchase some components for less than the listed prices, and I chose the 7900 XT because its 20 GB of VRAM appeals to me more than newer 16 GB alternatives. I also prefer the AIO for its appearance. The CPU and memory are the parts I'm least certain about. Is this a sensible build, or would you change the processor, cooling, graphics card, RAM, or storage?

For gaming, the Ryzen 7 9800X3D is generally the better-value choice and can even outperform the 9900X3D in games. The 9900X3D makes more sense when you regularly run heavily multithreaded productivity workloads; simply keeping lots of browser tabs open doesn't really justify the extra cores. A 9800X3D should handle gaming, streaming, and normal multitasking comfortably.
A 360 mm liquid cooler isn't necessary for either of these processors. A good air cooler, such as a Phantom Spirit-class cooler, should be enough and would cost much less. Keep the AIO if the look is important to you, but it isn't a performance requirement.
The memory situation is understandable, but 32 GB should be usable for gaming, streaming, and heavy browsing unless your workload is unusually extreme. If you can find a reasonably priced 64 GB DDR5-6000 kit, it would be a worthwhile upgrade for multitasking, but don't pay an excessive premium for it. More RAM is the appropriate way to improve that workload, not moving from an eight-core gaming CPU to a higher-core model.
The storage can be kept if you genuinely use the capacity. The existing 1 TB SSD and hard drive don't need to be replaced, and adding a 4 TB NVMe drive is reasonable for a large photo and video library. The 1 TB hard drive may be slow, though, so it makes more sense for backup or archival files than frequently accessed games and media. Also compare the RX 7900 XT against current-generation cards at the actual prices you can find; its 20 GB of VRAM is useful, but a newer card may offer better performance or features for similar money.
That makes sense. I was choosing the 9900X3D mainly for longevity and multitasking, but if the price difference is small I may still compare both before deciding. I hadn't realized that browser tabs mostly benefit from additional memory rather than more CPU cores.
