I don't think there's any real benefit performance wise in having FS installed in it's own SSD separate from the OS. That seems to be a remnant from of the old days when hard drives was all there was, but unlike HDs, SSDs can be accessed by several processes at a time with no significant performance hit.

Personally, I would pick one with an I5 12600K plus DDR5 RAM in a few months when there's more DDR5 kits to pick from.

Ouch. I'm afraid those OOM issues won't go away with the new machine. Not if you stick with FSX since it's a 32 bit application and will only allocate 4GB tops. All those addons are simply eating up all of your FSX VAS space. I think I read somewhere the steam edition of FSX is a bit better at managing memory. Not sure though. If you're running out of VAS your only options are to lower your settings and/or disable addons

Thanks Gerard

I don't know how a chipset would make any difference performance wise. But anyway. I'm not mentioning overclocking because the OP doesn't seem interested. Apparently that 8700K has a great Turbo boost and according to this it's able to hold 4.3GHz at full load. I would expect it to hover around 4.5GHz in FSX which is significantly more than the 3.8-3.9GHz of the 3770K. All in all, adding up clocks, IPC & RAM speed that Alienware rig could easily be a 40% faster than the 3770K. I dunno, maybe if Marcel tells us exactly what he means when he says he can't fly over dense sceneries, what FPS he's getting there and some more detailed info like the settings he's using, we can determine whether his performance issues can only be solved adding raw power or there's something else going on

Correction: that would be the IPC increase alone. Considering the higher stock clock & turbo of the 8700K and the (I assume) faster RAM of the Coffee Lake system, the performance increase will probably be more like a 25 - 30%. Whether that's worth it only Marcel can say. But again, I'm pretty sure his performance issues are not hardware related

No offense, but your logic is backwards. Newer systems struggle almost as much as older ones precisely because FSX can't take advantage of most of the novelties in those new systems. The single core performance between Marcel's CPU and that 8700k is also about a 15% and that won't get you from needing to turn down all your settings to being able to max them out. Not even close. Anyway, I think it makes sense to try the reinstall before getting a new rig. He can always transfer the new install to the new machine if he decides to go for it

If the OP isn't running stuff that is taking up more than 12GB plus FSX, 4K and/or tons of SGSS, your points are moot, and if he does he simply needs to shut down a few chrome tabs or lower those AA settings. He mentioned he started experiencing issues after installing one plane, so it's most likely not a hardware problem. The truth is that more cores, RAM, memory channels, L3 cache and most likely GPU power will not help at all here. So Marcel, if you were planning on doing a fresh install in your new machine, try doing that on your current one before you throw a couple grands down the drain

True, but have you considered you might be losing track of what the OP's problem is?

I'm skeptical about that. Can you please provide a link to those tests?

You don't need a new computer. You won't fix your performance issues by adding more cores, RAM or GPU power. Your current machine is already almost as good as it gets for FSX.

Why separate drives? That sort of made sense with mechanical HDDs, not really with SSDs

Get a single 240/250GB SSD to maximize value. A Sandisk SSD Plus, Mushkin Triactor, OCZ Trion 100 or 150, Kingston SSDNow,... the cheapest one will work just fine

Have you run some benchmark on that SSD after migrating? Did you check if the partition is aligned properly? Try AS-SSD

Did you install Windows with the mobo set to IDE? Because it looks to me like that's what causing your headaches. If that's the case you can fix the problem with this, and then you should be able to use your SSD at it's full capabilities http://www.everything-microsoft.com/2010/05/25/how-to-enable-ahci-in-windows-7/
