Based on what I have seen in the past, LM rarely introduces essential new features with incremental upgrades of particular versions of P3D. They are mostly aimed at Sim Director. I have been using version 3.3 for quite some time, since upgrading to 3.4 was basically pointless. For the record, I am only using 3.3 because I was forced to reinstall P3D from scratch at one point due to some PC issues that I was experiencing.

Hi Eddi,
Always happy to help. Regarding upgrading, the minimum is of course the Client. I do not recall the list of changes anymore

Here is the list of changes: https://www.prepar3d.com/news/2016/09/113700/
But I do not see relevant changes in Scenery content for 3.4 and also in 3.3 there is only a fix for "problem with an installation pass issue". So I think I will update only Client and Content as these have the most changes.

I will follow this tutorial as it seems very good and accurate: http://www.prepar3d.com/forum/viewtopic.php?t=120861

By the way here are my computer specs just for your information:
Windows 7 x64
Intel i5 4670K overclocked to 4,20Ghz
8GB DDR3 800Mhz
GTX 980Ti 6GB

Ah yes, so it does not look like that even Content would bring too much of improvements. You could always upgrade in two steps as well, making a decision depending on how the first step went.
Btw. your specs should run 3.4 similarly to 3.2.

Cheers
