I am reading more and more enthusiastic reports from people who are flying in Aerofly FS 2 with the Oculus Rift. I currently have an i7 4790K@4.5, 16 GB RAM and a GTX780 with 6 GB VRAM and I am thinking about getting the Rift for Aerofly FS 2.
Now I've read that going from an 4790K@4.5 to a 7700K@4.2 or OC'ed to something like 5 (and of course a new motherboard) will make a difference but not a huge enormous difference since the Ghz are pretty close. Replacing my GTX780 with a GTX1080 however should have a bigger impact. I am used to GPU upgrades NOT having an impact but that is with FSX and P3D... It seems that for modern games and I think also for Aerofly FS 2 the upgrade to a 1080 will make a difference. And it would also make my computer good enough for the Rift.
Long story short: is upgrading my 780 to a 1080 enough to enjoy the Rift to the fullest(!)? Or do I really also need to get a new CPU...? The latter would mean I have to get an entire new PC plus the Rift... If possible 'only' getting a 1080 with the Rift sounds better (and expensive enough already).
Any ideas on this? Someone here who has experience with a similar switch?
