NVIDIA RTX 50 SERIES - Technical/General Discussion

With the 5080 costs though you would be far better looking for a used 4090 for not much, if any more.

Cheapest 4090 I have seen is £1600 on ebay. With shortages and the fact it's faster than a 5080 this price won't drop at all.

I would never spend £1600 on a used graphics card personally that will have no warranty...

I have had 3 graphics fail on me out of around 20 or so in the past few decades.

There is never a guarantee of how a used GPU was treated etc. For me it's new or nothing.

I built a SFF gaming rig for my oldest son in a Fractal Ridge with my old 5800X3D and the 5080 he managed to get at launch...and have learned that heat-soak is no joke. Lol

He has a spot in his entertainment center where the finished PC looks awesome, (horizontal orientation) but the cubicle it sits in is closed on all sides with only the front open.

CPU temps were fine (not great, but fine) under stress testing when it sat on my floor, but unmanageable after less than ten minutes of 4k gaming in his entertainment system.

The 5080 is blowing straight through the whole case (which is great for the 5080) but the Thermaltake low-profile cooler can't move that hot air fast enough to keep the CPU cool....particularly since that air doesn't get far before it gets pulled through the GPU again, reheated and shoved back into the CPU intake under the rig.

We have ordered two PWM blower fans to mount in the top of the cube in the back corners and we are also going to cut a 140mm hole in the shelf it sits on and install a fan directly under the CPU, feed cool air from the much larger cubbie below it. All fans will be connected to the PC motherboard with extensions.

So 140mm intake. Two blower fans as exhaust. I hope the blower fans move enough air at a low-enough speed that they don't have to be anoying.

FWIW, the 5080 seems to deal with the heat build up well. -probably because the CPU gives up and starts downclocking hard well before the 5080 cooler has a problem.

True but then again 24GB of GDDR is a bit overkill as is a 512bit bus, the 5090 is closer to a professional grade card than a gaming card, a bit like the Titan class of cards used to be.

The 5090 is a great card if price is no object, unfortunately when price starts to get factored in things start to take a turn for the worse.

But... If Reddit is anything to go by we all need 64gb vram to run even doom from the 1990s. Apparently 16gbvram can't even boot windows. /S

Seriously though. The amount of idiots on there that claim that 16gb vram won't run anything at 4k is hilarious. My 3080 runs 4k amazingly well with 10gb.

Could get an AIO for the CPU and mount it outside of the cabinet, maybe at the back where you can't see it

That's a good idea, but won't work in this instance since he has mounted this to his wall and there's not even room for cables back there. (The cables go straight into the wall before coming out of the wall near the places they need to go.)

I also think the heat build up would get to the 5080 eventually. The chassis was too hot to grab by hand at one point.)

Woah woah woah, can you run Skyrim in VR with all the high res texture mods?? If not = trash card.

Meanwhile, in reality, the solution to cards not working in super niche scenarios is … doing whatever nominal thing is necessary to avoid those scenarios.
 
Has anybody tried reflex 2 yet or is it still not available? I know it wasn't available on the review drivers but it's bad crack imo advertising it as a feature of the card for it to not be available on launch.

Agreed. It could have been kept at 384bit for gaming, be a slightly smaller die, and I reckon gaming performance would be unchanged from the current 5090.

I have seen 2 go for £1350 in the last week on this forum. I have not had a single graphics card, new or used fail on me since my Ti4600 in 2004.

For me, at the price I got my 5080 Vs what I could have gotten a 4090 with warranty for, I saved £500, and in the games I play the "quicker"ness of a 4090 is in single digits.

When the reviews first dropped and all the 4090's were gone I was kicking myself, but actually I think I ended up with the better choice.

That's totally fair. I never said my opinion is the right and only opinion. You do what's best for you and if you're happy that's awesome.
