I would suggest getting a case that has a set of inbuilt (typically vertically-oriented) expansion card slots positioned a distance away from the regular expansion card slots, mount your graphics card there, and connect it to the motherboard with a PCI-E riser cable. It's what I did and I kicked myself for not doing it years prior. I have no experience with PCI-E 5 cables, but I've a PCI-E 4 riser cable from Athena P…

Can you link to an example case and riser cable?

I shouldn't have to link to the cable given that I said "Athena Power" and "Newegg", but sure, here you go. [0] Their Newegg store is here. [1] (They also sell that cable in different lengths.)

The "away from motherboard expansion card slots feature" isn't particularly uncommon on cases. One case that came up with a quick look around is the Phanteks Enthoo Pro 2. [2] I've seen other case manufacturers include this feature, but couldn't be arsed to spend more than a couple of minutes looking around to find more than one example to link to.

Also, there are a few smaller companies out there that make adapters [3] that will screw into a 140mm fan mounting hole and serve as an "away from motherboard" mounting bracket. You would need to remove any grilles from the mounting hole to make use of this for a graphics card.

[3] Really, they're usually just machined metal rectangular donuts... calling them "adapters" makes them sound fancier than they are.

The only reason gaming doesn't use all the VRAM is because typically GPUs don't have all the VRAM. If they did then games would somehow find a way to use it.

Game engines are optimized for lowest common denominator, being in this case consoles. PC games are rarely exclusivities, so same engine has to make it running with least ram available and differences between versions are normally small. One normally uses some ultra texture pack to utilize current gen card's memory fully on many games.

Consoles would have more VRAM too if these cards had more VRAM. It's not like they're made separately in isolation.

If anyone thinks they are having laggier controls or losing latency off of single frames I have a bridge to sell them. A game running at 60 fps averages around ~16 ms and good human reaction times don’t go much below 200ms. Users who “notice” individual frames are usually noticing when a single frame is lagging for the length of several frames at the average rate. They aren’t noticing anything within the span of an a…

You think normal people can't tell? Go turn your monitor to 60hz in your video options and move your mouse in circles on your desktop, then go turn it back to 144hz or higher and move it around on your screen. If an average csgo or valorant player where to play with framegen while the real fps was about 60 and the rest of the frames where fake, it would be so completely obvious it's almost laughable. That said the 50…

>If an average csgo or valorant player were to play with framegen while the real fps was about 60

That's just it isn't. This stuff isn't "only detectable by profession competitive gamers" like many are proposing. It's instantly noticeable to the average gamer.

Nvidia wants you to buy their datacenter or professional cards for AI. Those often come with better perf/W targets, more VRAM, and better form factors allowing for a higher compute density. For consumers, they do not care. PCIe Gen 4 dictates a tighter tolerance on signalling to achieve a faster bus speed, and it took quite a good amount of time for good quality Gen 4 risers to come to market. I have zero doubt in my…

In the server space there is gen 5 cabling but not gen 5 risers.

    > gen 5 cabling
Do you mean OCuLink? Honestly, I never thought about how 1U+ rackmount servers handle PCIe Gen5 wiring/timing issues between NVMe drives (front), GPUs/NICs (rear), and CPUs (middle).

I will be astonished if I'll be able to get a 5090 due to availability. The 5080's comparative lack of memory is a buzzkill -- 16 GB seems like it's going to be a limiting factor for 4k gaming. Does anyone know what these might cost in the US after the rumored tariffs?

4k gaming is dumb. I watched a LTT video that came out today where Linus said he primarily uses gaming monitors and doesn't mess with 4k.

Almost no one plays on native 4k anyway. DLSS Quality (no framegen etc) renders at 1440p internally and by all accounts there is no drawback at all, especially above 60fps. Looks great, no noticeable (excluding super sweaty esports titles) lag and 30% more performance. Combined with VRR displays, I would say 4k is perfectly ok for gaming.

There are good 4K gaming monitors, but they start at over $1200 and if you don't also have a 4090 tier rig, you won’t be able to get full FPS out of AAA games at 4k.

I still have a 3080 and game at 4K/120Hz. Most AAA games that I try can pull 60-90Hz at ~4K if DLSS is available.

Most numbers people are touting are from "Ultra everything benchmarks", lowering the settings + DLLS makes 4k perfectly playable.

Similar CUDA core counts for most SKUs compared to last gen (except in the 5090 vs. 4090 comparison). Similar clock speeds compared to the 40-series. The 5090 just has way more CUDA cores and uses proportionally more power compared to the 4090, when going by CUDA core comparisons and clock speed alone. All of the "massive gains" were comparing DLSS and other optimization strategies to standard hardware rendering. Som…

I started thinking today, when Nvidia seemingly keeps just magically increasing performance every two years, that they eventually have to "intel" themselves, where they haven't made any real architectural improvements in ~10 years and just suddenly power and thermals don't scale anymore and you have six generations of turds that all perform essentially the same, right?

There is one major 4 letter difference - TSMC. Nvidia will get tech process improvements until TSMC can't deliver, and if that happens we have way bigger problems... because Apple will get mad they can't reinvent iPhone again... and will have to make it fun and relatable instead by making it cheaper and plastic again.

Because if two frames are fake and only one frame is based off of real movements, then you've actually lost a fair bit of latency and will have noticably laggier controls. Making better looking individual frames and benchmarks for worse gameplay experiences is an old tradition for these GPU makers.

If anyone thinks they are having laggier controls or losing latency off of single frames I have a bridge to sell them. A game running at 60 fps averages around ~16 ms and good human reaction times don’t go much below 200ms.

I can and do notice when a driver update or similar switches my monitor's refresh rate or mouse polling rate down. In the game I play most there is an inbuilt framerate test tool to see what the best framerate you can notice the difference between visually is. I and many other players are consistent (20 correct in a row) up to 720fps.

> will be two times faster [...] thanks to DLSS 4 Translation: No significant actual upgrade. Sounds like we're continuing the trend of newer generations being beaten on fps/$ by the previous generations while hardly pushing the envelope at the top end. A 3090 is $1000 right now.

5090 has 2x the core, higher frequencies, 3x flops. You got to do some dd before talking

Which flops? For AI flops it’s only 25% faster than 4090 (3352 tflops vs 2642 tflops)
