I'm looking to upgrade my CPU and MOBO for FSX. Currently I'm running a 3570K at 4.5GHz with an Asus Maximus V Formula Z77 Mobo - it runs fine but I wouldn't mind boosting FPS a little on approach. I've been thinking about getting the 4790K and Maximus VII Formula, but I've also be eyeing the Haswell-E CPUs - specifically the 5820K and 5930K. What kind of overclocks are being achieved on average with these 3 CPUs and how are they performing with FSX. I know the 4790K is pretty solid, but the extra cores with the -E series will help with FTX global/vector and my other addon scenery. Is it even worth upgrading now, or should I wait until next year when Broadwell and Skylake hit the market? Thanks in advance for any feedback. 

The 4790 is considerably faster on a per-core basis than the 5820 (6 cores) or 5960 (8 cores), and in CPU benchmarks it excels. Not to mention a LOT cheaper - the 5960 is over a grand vs $300+ for the 4790.

 

However, additional cores would be interesting to try. My rig (4770K running at 4.2 GHz) has cores 1,2, and 3 often maxed out, with core 0 running at 50-percent doing "other stuff". Two additional cores running addon stuff may be beneficial.

I might be wrong but I think you need to watercool to get the 6 and 8 core chips to a decent overclock.

 

A full platform upgrade with expensive CPUs and DDR4 plus potential cooling expense in my opinion is not worth it, regardless of whether it gives you a few fps etc...and I haven't read one story about anyone going Haswell-E from a 4ghz+ quad core and being impressed.

 

I believe it can help with texture loading but that's all.

 

At this point (4790k/970/2400c11/SSD) I think I will be waiting a long time to upgrade just for FSX.

Just wait for the new architecture - Skylake - the "tock" in the tick tock cycle of Intel's roadmap since 07. Releasing sometime 2015.

 

I'm kinda in the same boat (older CPU though). I'm probably getting a gtx 970 because P3D and xp10 aren't doing so well, same with BF4. But at some point I'll need to upgrade my almost 4 year old system.
