Buy a 5090?

[witwas]

My 4090 will end it’s warranty period in a couple of months. This got me thinking on buying a 5090. As my card still has some months of warranty left it should be doable to sell it around € 1500.

I am not necessarily looking for more performance or 15fps extra. My 4090 does the job perfect in VR. I just don’t want to end up in a year with a broken 4090 and have no ‘residue’ value left on an expensive card.

What would you do?

if the 4090 works for you and DCS is your primary game / you don't care about the features of 5x series card ... just hang on to your 4090... i have a 1080ti that is still running from the factory (now in my daughters PC) but and i don't expect that my 4090 will have a much shorter life than that, which is what 8 years on or so ...  when i moved from a 3090 to a 4090 i wanted the extra FPS for VR and i did sell that at the time ... but i was unhappy with the performance ... for DCS in VR.

I haven't really had a card longer then 2 or 3 years because it was always a significant bump up in fps and resolution (I have to agree on the marginal bump up from 3090 to 4090). I am now happy with the resolution and fps in DCS and Falcon BMS with my quest 3. 

If the 4090 is designed to last 8 years i also see no reason to go to a 5090. I also don't overclock and maybe use my pc on an average 5 hours a week.

I can’t gaurentee an 8 year life but as I said my 1080ti is still going and it is overlocked and gets gamed on nearly every day…

Honestly?

If the reason is being afraid that your RTX4090 goes kaput right after the warranty expires, then I'd keep the money.

The only thing that I would strongly recommend is (if you haven't done it already) to undervolt your RTX4090, and A.S.A.P.

Every single GPU, whatever segment and model, ALWAYS comes overvolted from factory.
The silicon lotery, time constraints for QC, materials and customer assistance costs, these all play a role. And so the bean-counters at each manufacturer decided long time ago that GPUs better get some hefty extra (i.e, excessive) voltage in them, so that a LOT more of them work at the announced clocks once out of the production chain to testing, then onto the retailers/shops. They're enforcing GPUs stability with factory announced clocks that way, lifespan of the product be damned (society of consumerism, there you have it).

By undervolting your RTX4090 you'll get at least a 20% reduction in power consumption, and only a ~2% reduction in performance (extremely good trade-off).
This will put less stress on the whole circuit, make it run cooler, which also helps stability (less stuttering) and especially - which is what you're looking for - prolongue its lifespan.
Most times tremendously improved, in such ways, over "stock".  And there are no downsides to it.

Everyone should undervolt their GPU, because that's how it should have been from the start, but alas.

Various undervolt tutorials specific to the RTX4090 in youtube. Among plenty others, this one here is a good example:

Very good advice.

With a slight undervolt my 4070ti Super runs 10°C cooler and the difference is 1-2 fps at most.
