I know there are more forum posts on this topic than mushrooms after the rain but I'm not a hardware guy so I'd appreciate some advice on what to buy or not to buy. Right now I don't have spare dough for a brand new computer but I'd like to upgrade performance and run P3D v4 a bit better than v3 if that's even possible without buying a new one. I have about 800€ to throw at some new hardware. I already almost decided to buy GTX1080 and 16 gigs of RAM or GTX1080Ti and no RAM but now reading other posts I'm not sure anymore that the gains would justify 800€. In v3 I'm bottlenecked by CPU @ 4.5GHz (baby we couldn't get much higher) so new GPU probably wouldn't help that much, I don't have 4k or triple monitors after all. I use TrackIR and anything below 40FPS becomes a stutter fest, that's the main problem I have right now. What hardware should I buy to even run v4 without running out of RAM or Vram and what hardware upgrades would gain me some more FPS. I use a lot of payware (ORBX, A2A, PMDG, AS2106, .. all shebang). I know bigger and faster is better but what would you recommend me doing considering my current setup and the amount of money to spend? Thank you!

Definitely more RAM would help your current system. For my new build I'm planning a 32GB kit since users are reporting flight sims using around 20GB or more of RAM. Consider a 16GB (2x8) or 32GB (2x16) DDR3 2133MHz kit.

Are you sure you're optimizing your sim settings for your hardware? You can always spend more money but "maxing out settings" like some people always go on about is not simming.

Thanks!

My settings are fine, I just want to know with what hardware upgrades can I run my sim better, considering the amount of money I have to spend.

Regarding the RAM.. as I understand, the amount of RAM sim will utilize is in correlation with the total amount of RAM you have.. generally 16GB should be enough.. in that case sim would clear some RAM before it'd reach 20GB. That's my understanding at least.

The only thing that sticks out as a real performance liability with your config is the ram speed. Might be hard to find these days, but try to get that to at lease 2133 c9.

You might also get a lil bump in performance with a gtx1070 upgrade.

 

I have a similar setup as yours and can run 3rd party airports, orbix stuff, Active sky 2016 and the PMDG 747 with no performance issues, save the dynamic lighting stuff. Oh, and that's on 8GB of ram.

1070 or 1080 if you're running 1080p. I thought about saying go for a new motherboard, CPU and RAM but the 4790k still has life left in it.

And I'll add to my original response... When I started trying new cards in January, the jump from my 970 to the 1070 was a decent one. I tried a single 1070, SLI 1070, a 1080 and 3 different 1080 tis. I think the 1070 is my favorite card of all of them, it packs a heck of a punch. I used both the Asus Strix and EVGA SC 1070. EVGA won me over with their customer service.
