It's time for a new motherboard/CPU, I guess? I'm just not sure whether a new CPU will make that big a difference for X-Plane (will it?), and the computer runs everything else I need just fine.
My system. 1st gen Haswell I5 Z87 Motherboard (no over clocking) with GTX740 video card. On X-Plane getting 45-65 FPS with some fairly high settings and HDR turned on. Before I turned up some rendering settings I was getting 100-120 FPS!!!
The most glaring difference between our systems is your CPU is several generations older than mine. Your graphics card would likely eat mine for lunch.
IMO a good recommendation to follow is do not to upgrade the CPU unless improving by at least 2 generations. Which in your case that recommendation would be met.
OBTW, the i7 930 was released in Feb 2010 so in CPU generation terms your system is more than 5 years old.
Some food for thought.
The CPU utilization numbers quoted can be very misleading. Consider a 4 core CPU with one core maxed out. This will be reported as 25% used (1 out of 4). But in fact for the particular job the CPU is running as fast as it can (single core work load). Instead use the task manager and look at what the individual cores are doing before making a decision to upgrade.
Also get an utility to look at the Graphics card utilization. In my own case I was considering an upgrade from a i5 to i7 which would have been expensive with the $$ on the i5 being wasted. However the GPU utility said that my old graphics card was totally max out. Spent less $$'s with better results where it could do the most good on a newer graphics card (in my case).
In your case the graphics card isn't going to be the bottleneck. IMO it's more likely that in your case performance can be gained by lowering some rendering settings to better match the CPU/MB combination.
IMO sometimes people buy more PC than they really need because of future fear. So if looking to save real $$'s on a flight sim system don't chase bleeding edge technology unless there is no other way to meet the systems goals. But the key here is to have honest "goals/expectations" for the system. THEN upgrade what is needed.
If looking for an option to consider. A new budget motherboard ($60) with a Haswell Pentium CPU (yes a dual core CPU) can be purchased for less than $60 (that's $120 total!). Reuse the memory and other hardware that you have now. So this offers a very low cost option to find out just how much a new CPU could help. One of the nice things about this option is it has some affordable upgrade possibilities (i3, i5, i7).
Or you could look at a budget MB/CPU as a "bridge" to future technology. IMO the key to making this work is to not invest toooooo much $$ on the bridge.
On to FSE topics. At 40K haven't you already earned about 20% of the purchase price of the airplane? IMO this is very good especially if compared to the cost of shipping. IMO you should give yourself a pat on the back for a job well done.
