My 3090s in NVLINK/SLI are enough for what I need them for work, nothing so far is available to replace them.. DLSS3 to me is a scam and not real world hardware performance increase, it's fake frames made with software, I'm paying for hardware not software gimmicks to fool the average Joe that knows nothing about hardware.
Also I'm looking at getting a pair of Nvidia RTX A6000's ADA threw work if they will pay for one I will pay for the other to build another workstation. So far not looking promising as the in house software we use needs the Devs to make it work without NVLINK as these A6000's ADA don't have NVLINK and the software we use is setup to use NVLINK and even when it sees two cards not linked will not pool VRAM or CUDA cores and sees them as two separate cards so basically 48GB VRAM projects only can be used so no better than 2x 3090s that do the same 48GB VRAM in NVLINK. The devs are working with 2x4090s as we speak and have been for a few months now and they are finding it difficult to get the applications to work correctly and use both cards, they can send workloads to each card but that limits us to 24GB VRAM to each card projects again and the idea is to be able to run larger projects than 48GB and even larger ones that's why if they can make it work it will open up A6000 ADA to 2 x 48GB =96GB projects then and what we really want, 48GB is causing us problems for certain projects now and we are trying to future proof and even contacting Nvidia about this issue and asking if the new generation will support NVLINK they don't reply as they have clearly moved NVLINK to their higher end gear and we need PCIE cards not their gpu server gear that supports NVLINK. It's a huge mess really and Nvidia is shooting themselves in the foot with what they are doing.
Regarding gaming I have no interest in updating for that as most games available now I have zero interest in and the ones I do use are fine on 3090..
My gripe with this generation is they lack NVLINK and making a mess for many people that use them for professional work. If I end up with two A6000's ADA and the Dev team can make them work on our applications then the 3090s will go up for sale and I will grab a single 4090/ti and stick that in the HTPC and make it the main gaming system and sell the 3090 in that too, but for now it has to stay as it's a spare 3090 I may need if one goes wrong in the main rig and need to RMA it.
Nvidia really created a mess for us that use them for work and the A6000 Ampere is £4700 each and ADA is $6800...at current prices if you can find them in stock.. May have to wait till next generation of cards if they stick NVLINK back in or just call it a day and stick to the 3090s or grab a pair of A6000 Ampere versions as they have 48GB and NVLINK .. but a bit of a side grade for more VRAM but no performance increase but maybe that's the next update path as nothing else is available that does what we need.
Anyways we will see so far it seems we are stuck on 3090s and not much we can do as the applications we use also use cuda and we can't even go AMD with their workstation class cards either..
Gaming is the least thing I worry about when updating gpus and only one game that I even care about is MSFS and even that is not really showing worthwhile increases on 4090 without DLSS3, I would never use DLSS3 on MSFS and MSFS still needs faster CPUS too and even CPUS are not worth updating right now from what I have, with the costs of a decent motherboard and DDR5 RAM.. The whole pc market is a mess and maybe time to step away for a few years and see what happens again, the costs and improvements for the money is not there anymore, its stagnated horribly and basically any increase you get now you are paying more for it than before. Inflation in the pc market this gen is a doubling of prices on many of the components, just have to look at the comedy that is 4080 and 4070ti and even the 7000 series gpus from AMD, the 7900 series is really 7800 and priced like 7900/6900 series..
