i9 9900k vs 5900x
You’ll likely see a noticeable improvement over 1440p, especially compared to 1080p. The higher resolution will make details sharper and more defined.
It depends on how you define a "big difference." Your choice of games, overall system specs, etc., matter. As a rough estimate, you might see about 30 extra frames per second at 1080p and 20 more at 1440p, but these are just guesses.
Yes, playing MMOs is generally possible, though not always ideal. Even when the 5900x is strong, frame rates are often high enough that performance differences feel minor. However, in MMOs single-threaded performance usually becomes a bottleneck during intense multiplayer battles or complex physics scenarios, making the 5900x more apparent. Instead of dropping to 70 fps, expect it to fall to around 80 or 90.
It's expected the variation in average frames per second will likely range from 10 to 30, influenced by the game and settings. When playing at 1440p on an RTX 3090, the difference should be barely noticeable. For instance: distinguishing between 60fps and 144fps is definitely possible! Similarly, telling apart 160-170fps versus 180-190fps will be very subtle if not nonexistent.
I own a system with 9,900 GB storage, 3,090 components, 32 GB RAM, and a processor clocked at 3600 MHz.
You use a variety of games and stream, which can ease the CPU/GPU workload when upgrading to 5900x.
These games are already very high-performance FPS titles for the 9900k. If you're streaming, you're likely using nvenc. Improvements are expected, but it's hard to say exactly how much better they'll be.
