Nice setups...all of you. Here is my rig:OS: Windows 7 Black Edition (Ultimate)CPU: Intel i7 950 BloomfieldMotherboard: EVGA X58 Classified 3Video Cards: 3x EVGA 465 GTX in SLiRAM: 24Gb Triple Channel DDR 3HDDs: x4 500GB Drives, 1TB Drive, 2x OCZ 120GB SSDsOptical Drives: HP BD/DVD+R/RW Drive, HP DVD+R/RW DriveMonitor: 2x Acer X223w, 1 Acer G215HKeyboard: Logitech G510 KeyboardPSU: Corsair AX1200Case: Corsair Obsidian 800DMouse: Logitech Darkfield Performance MXSound: Logitech Z-5500 THX 5.1 Speaker Systemhttp://valid.canardpc.com/show_oc.php?id=2142085Monday, I will switch out the processor and motherboard for a EVGA Classified SR2 Dual Processor Motherboard and Two Intel Xeon E5506 Nehalem 2.13 GHz Quad Core Server Processors. After that, I will not work on upgrading the core system for a long time. The goal is to eliminate every bottleneck FSX can run into.

Did I understand it wrongly, or did you just say you are gonna put two Xeon CPUs E5506 in your next computer to eliminate bottlenecks for FSX?

Yes, I was about to ask the exact same question but Srdan beat me to it.

Haha, it rolled off the tongue so casually

Yup. :)The EVGA Classified SR 2 is a Dual CPU Motherboard:http://www.newegg.co...N82E16813188070Too bad I can't directly attach an image here...Alright... here is the Classified SR2 motherboard.... notice it has TWO CPU Sockets for dual CPU operation....

Well, that's going to be a downgrade over your current I7 950 for what FSX is concerned man. You are adding more cores, but those run quite a lot slower. Since FSX can't use that many cores your current system is indeed better for FSX than that SR2Money doesn't seem to be an issue for you, and given that you have a tri-SLI why not LGA2011 + I7 3930K or I7 3960X?

Well, using the entire ORBX US package, the PMDG 737 series, REX and the sliders nearly at max, I cannot understand why the frame rates are still choppy and 36,000ft. Also the PMDG 737 is constantly freezing during flights, even with the SP1 update. If my current setup isn't the issue, then what is? Right now, I have a Intel i7 960 3.60ghz (brand new in the box) just sitting on my desk. It was going to be installed when I came across some extra spending money.Please don't ask if I am running Acceleration.... I am.

Believe me. those Xeons will only make matters worse. FSX has many limitations:- Can't take advantage of more than 3 cores. Not in a way that will help with your choppy FPS- So what you need is fast cores not more cores. The newer I5 2500K & I7 2600K or I7 3930K - I7 3960X are a much better option, you may want to consider overclocking.- Your freezes are most likely a virtual memory thing. FSX is a 32 bit application and has a 4GB limit. Are you using any tweaks like increasing LOD?- While SLI is needed to run multimonitors, it will do nothing for your frame rate in FSX

Dario is 100% right. Probably the fastest FSX computers in the world have been tested here for FSX with the FSXMark11 Benchmark. Just copy what you see taking top positions in the test results. You can have excellent performance in FSX, but not with a i7 960 or Xeon CPUs, but an overclocked Sandy Bridge and a fast Nvidia 500 series video card.https://docs.google.com/spreadsheet/ccc?authkey=CMSSocoI&key=0AuiXjW8fJyDrdC1KZm5fSlJYdnJBaXRRclFuU0U3WUE&hl=en&authkey=CMSSocoI#gid=0Kind regards,

Um yeah, everyone else beat me now to it! What you are planing with Xeons, thank God you posted here, so that we can tell you that it's a really bad plan for FSX. The setup you have is in general low config for FSX and can't be expected to run it smoothly - I am not wondering that your frames are poor and you get stutters.What you need is a CPU that can run 4 cores and 5Ghz or about and a really fastest GPU you can afford, something like GTX580, but again, single core GPU, not something like 590.2700K, GTX580, 8GB of 2133mhz low latency RAM and a fast SSD is what you should be aiming for. That and really good cooling to be able to overclock the CPU. That is gonna get you one awesome FSX performance.

Well said everybody!

Oh and btw. I just wanted to add something: great plan if you are building a server! Except those triple-GPUs then of course!

AS everybody said, just jet an i5-2500k and you´re out of trouble.

Alright, let me get this straight.....An i5-2500k is faster than a 3.20GHz, 8MB Cache i7-960?If this is the case, then my current X58 Classified 3 and the upcoming Classified SR2 is worthless when running FSX! I should have just kept my Intel Core 2 Quad overclocked and my EVGA 650 motherboard.... I had no issues with FSX with that setup...Trust me guys I am trying believe what you all are saying, but something is missing... or it's something I am not getting.

Oh and btw. I just wanted to add something: great plan if you are building a server! Except those triple-GPUs then of course!

The Idea was to build a sever-based workstation....the ability to run as a desktop and a server. The current setup may look like I am running 3 GPUs in SLi, but actually two is in SLi, one does the Physx work.It makes Crysis 2 and Battlefield 3 on the PC run like its is on a console.... However, I still get issues with FSX, a simulator nearly 10 years older.Either way, if it doesn't work the way I planned, then I will just build a server out of the Classified SR2.BTW: Gentlemen.... I forgot to mention that it isn't FSX that freezes in general, it is when I use the PMDG 737 series that it freezes on and off at cruising altitudes.
