Hello,

I am using a GTX 1070 currently and am wondering if an 8GB card will be sufficient in the near future with P3D. P3dv5 has made things more balanced between the cpu and gpu, but with my vram approaching 8GB of usage in some situations, it makes me wonder how much longer my 1070 will do the job. The price difference between an 8GB card and an 11gb is huge, even with the latest generation of GPUS.

I went from a 1070 to a 2080ti and I haven’t run out of vram, but I’ve certainly encountered a few situations where my 1070 would have.

The 2080ti was among the single most expensive things I’ve ever bought for my computer but I’m very happy with it.

As usual, sim upgrades drive hardware upgrades.  These days, you can't have too much GPU memory and power.

 

In flight sim i would say it`s the other way round,  Hardware has outpaced the sim software and is not used to full. Multi-threading was around in the FSX days but still not used as it should be, GPU`s less then 50%.

At this point hold off till the RTX3000 series cards come out, a few months time. They hopefully will have more Vram. I have an RTX2080 and can max it out no problem. 

I just become aware of the limitation with my GTX 1080 8GB card. My system is built around a i7-8700k overclocked to 4.9 and 32GB RAM.  I wonder if a new card with greater VRAM will be sufficient?  I don’t like the idea of a rebuild and the associated cost (motherboard, CPU, etc.) but don’t want a bottleneck. Is that what I’ll get by simply upgrading a video card?  What to do?

If you need to change your card before AMD announces their next gen cards in Ocotber (so you can make an informed decision as to Nvidia or AMD), try finding a used 1080ti which has 11Gb VRAM. That is what I did and it works well. 

Yeah my 1080 ti vRAM usage sits between 8 and 9 Gb @1440p and high/ultra settings.
