Hello,I have upgraded my computer this summer in order to run the PMDG 737 NGX even at addon airport a decent framerate. I can lock my flightsim at 40 frames per sec and it all runs more or less fluid, except for the NGX.These are my computer specs:ASUS P8P67 PRO Rev 3.1Intel i5 2500k @ 4.5 GHzCorsiar Venegance 8 (2x4) GB RAMEVGA GTX 560Ti 2GBCorsair A70 CoolerWestern Digital 1TB Black CaviarThe only device I didn't change was my Corsair HX520W PSU. My system runs quite stable - I used a conservative way to overclock my i5 - but I do wonder if a better PSU could be my bottle neck, if this makes logical sense at all?Only the PMDG 737 NGX Virutal Cockpit plus addon scenery bring my computer to its knees, no matter what is set in FSX. Everything else runs pretty stable, not shutdowns or BSOD, Temps are fine.Would a i. e. 650 Watt PSU bring any benefits? I am just trying to rule out everything.Thanks for any help!Christian

Hello.thanks for the info, that's what I was expecting. Everything is running, so unless I have got a few Euros too much on my bank account I'll stay with my old PSU. But I'll keep an eye on that 750 W PSU.Thanks! :-)Christian
