System upgrade - DDR4 vs DDR5

[Mace 1,955]

With frame gen in MSFS, a 4080 or 4090 makes the most sense.  For MSFS, the 4090 was the greatest upgrade I've ever done in flight sim, at least in recent years.

You mentioned MSFS so I wouldn't even consider a 3080ti.

You may be just as well off with a 4080.  MSFS will use all of the available vram, so that's why you're seeing max usage.  I will say though, with a 4090, I'm typically still only seeing about half the vram in use.  I run at 4K.  I need to load up FlyTampa EHAM and see how much vram is being used.  Or iniBuilds KJFK.

same.  FG was the biggest upgrade I've had in recent years.  Especially when combined with real (not just compatible) Gsync.  When I did my current build I decided back then to stick with DDR4 3600 memory.  If I were building today I'd go with DDR5, just because that's where the future gains will be made.

Make sure you measure it anyway.  I have been using large, full-size Coolermaster HAF932 and HAF-X cases for years, and was very unpleasantly surprised to find the ASUS 4090 GPU I got during the height of the shortages was *far* too long to fit into those big cases due to the placement of the non-removeable hard drive cages.  Most of the 4000-series cards are truly ginormous.  I was able to fit an nVidia 4090 FE GPU into the HAF cases, which I did for my MSFS/XPlane machine, but I had to very reluctantly go to a different case for my 13900K/4090 P3D build.

My previous build had a Coolermaster HAF case but that now encloses my secondary PC used for web browsing only. The build I propose to upgrade has a Corsair 750D case and there is about 15cm clearance between the current 3080ti GPU and the two intake fans at the front of the case.  There is one other intake fan in the base which draws in cool air from a tiled floor (a natural heat sink) and an exhaust fan in the rear.  The top has the two fan 115i pro AIO radiator.  I hope this will be enough to cool a gen 14 CPU and a series 4000 GPU but we will see.
