I've got a 4090 from 2023 that still runs everything at high settings, but I keep seeing people say the 5090 is a massive jump. Is it actually worth dropping the cash for 1440p gaming, or am I just fine keeping what I have? I'm mostly playing newer AAA stuff like Stalker 2 and Indiana Jones.
The practical answer is no, but there's one angle worth considering: a 4090 from 2023 is still pulling solid power efficiency gains from newer architectures, and if your monitor can actually display high refresh rates at 1440p (144Hz or better), the 5090 might let you hit those consistently in demanding titles where a 4090 starts to dip. That said, if you're happy with your current frame rates and settings, you're already in the sweet spot - the upgrade only makes sense if you've got a high-refresh display you're not fully utilizing or you're planning a jump to 4K in the next couple years.
Your 4090 is still overkill for 1440p even with the newest games cranked up, so honestly there's no practical reason to upgrade unless you're chasing like 240+ fps or planning to jump to 4K soon. The 5090 would give you better performance per watt and some nice headroom for future titles, but you're already sitting pretty with what handles those AAA games smoothly at high settings. I'd say save your money unless you're getting bored or want to future-proof for the next few years - the jump from high to ultra on a 4090 at 1440p isn't usually game-changing enough to justify the cost when you're already getting great frame rates.
If you're hitting stable frame rates at 1440p with high settings on a 4090, jumping to a 5090 is basically throwing money at a problem that doesn't exist. I've seen folks obsess over generational upgrades when their current hardware is already doing the job perfectly fine - the jump matters if you're eyeing 4K or running competitive multiplayer at ridiculous frame counts, but for single-player AAA stuff at 1440p you're already set. The 4090 will handle Stalker 2 and those newer games without breaking a sweat, so unless you've got cash burning a hole in your pocket or you're genuinely planning to upgrade your monitor resolution soon, keep what you've got and spend the money on something else.
Don't fall for the marketing noise around generational jumps - the math just doesn't work here. At 1440p on a 4090 you're already well past diminishing returns; the 5090 would give you maybe 30-40% more performance for games you're already running smoothly, which is money spent on overkill. Save your cash unless you're actually planning to upgrade your monitor to 4K or chasing extreme refresh rates, otherwise you're paying a ton for framerates you won't notice.
Save your money because you're already crushing 1440p - a 4090 is doing exactly what it's built for at that resolution! But here's something nobody's mentioning: if you're really itching to spend, grab a high-refresh 1440p monitor instead (like 240Hz+), because your GPU can actually push those frames and it'll feel like a massive upgrade without the hardware expense.
