FX8___ beats I5 for most things.
FX8___ are 8 cores and big 8MB L3 cache.
But even act as 4 cores for somethings (You need to read how FX works.) I5 has 6 cores for only best CPUs, 8400 & 8600K, and most are clock locked. (xxxxK are unlocked).
Intel's Hyper Threading (xxxxU i think) is not same as real cores. I've been dealing w/ HT since Pentium 4 and Xeon first had the option. Helps a lot for many things but not much for most others. In some cases HT CPU are actually slower then non HT CPU even when both are same class Intel units. Even enable/disable using "BIOS" settings etc can see this on same CPU.
Note that "frame rate" in a game means little... What
you really see are real frame for displays and many are ~60FPS
or less. IOW Screen Refresh rates = ~60Hz in OS Control Panel is more like 20-30FPS at best.
Any faster then that is smoke in mirrors to make points w/ benchmarking folks etc and GPU/CPU gets hotter for little to no results. Worse Display(s) can look bad too because of
frame tearing and other issues. Screen tears and other problem cause by high FR often get confuse w/ bottle neck whatever.
Toms hardware et al has covered this fact but very few read them and understand the Hype push by Nvidia EA etc. Many slam the stories are dump and have no clue, fan boys or worse Shills for Nvidia ATI(now own by AMD that loosing the ATI markings) etc.
Is why changing Video settings for most games matters a lot. Small setting changes can make a huge difference.
3D & VR are also related to screen refresh too. CPU/GPU pushing faster frame rates then Display can handle have same results but often way more obvious.
Or GPU is just dumping data to prevent tearing but CPU/GPU burning energy generating more heat making frames never shown.
