GPU and RAM - question

[talvikko]

I'm planning to build a new computer (primarily for DCS) and I have two questions:
1. Will I notice a real difference if I add 128 GB of RAM instead of 64 GB? (I know more memory is better, but if the practical difference is small, I don't want to spend money unnecessarily.)
2. Will I notice a significant difference between the graphics cards: RTX 5070Ti 16GB 256-bit vs RTX 5070 12GB 192-bit?
Of course, I realize that the 5070TI is more powerful, but I also want to spend my money wisely.
And importantly: I won't be playing VR. I don't need anything more than a monitor and a 1920x1080 resolution.

Have not seen DCS fill 64gb yet...but who knows in the future.

You should be good for a few more years with 64gb.

1 - No. DCS is nowhere near using 64GB of RAM and it won't be for, at least, a few years.

2 - Yes. 12GB is on the low end of VRAM amount for a 2025 card. You might not notice it right now, but it could start limiting you in a couple of years. If the price difference is not outrageous, go for the ti. More future proof, too.

3 - Yes. Both those cards will laugh at you at 1080p. Throw them a real challenge: 1440p should be a nice upgrade without breaking your bank.

I’ve yet to see more than low 50GBs of use in DCS, and that’s whilst in VR, running a number of other Apps such as Simshaker, Tacview.

So right now, more is probably overkill.  

If you don’t have an infinite budget, it’s probably more important to get a good CPU (9800x3d), PCI Gen5 drive, low latency RAM, a good GPU and then spend some time to optimise settings.

Having said that, if I were planning a new build, I’d certainly consider grabbing 128GB, “just in case”.
