AMD FX 8320 OCed to 4.8ghz. 16gb ddr3 AMD/ATI RX 580 Asus Sabertooth 990fx R2 motherboard. Water cooled with a Corsair H115i AIO. And I still lag like fuck hell on Guild Wars 2. Guild Wars 2 is intel optimized but WTF. I should be able to play it on Max settings without dropping below 60fps. I play on medium low with all of the fancy crap turned off and some times my fps drops as far down as 8-12fps. Most of the time it hangs around 30-40fps.
Crazy shit is my GPU usage stays around 20% and CPU usage of 15-18% across all cores. A much much more demanding game such as DayZ Standalone or Arma 3 will run 120fps+ all day long with the graphics cranked.
The Amd FX chips (Vishera core) integrated memory controller is absolutely horrible. It's the sole cause of dropped frames,significant FPS drops and horrible overall gaming performance on a non AMD optimized game. And AMD blatantly lied to us when they called it an 8 core CPU. It's a 4 core CPU with 4 threads. Same concept as an intel CPU with Hyper Threading.
The i9 9900K is currently the best CPU out there for gaming. Currently priced at $470.
AMD for computing/rendering or those few games out there that are optimized to run an AMD cpu. The best that AMD has to offer At the moment is the Ryzen 9 3900x which started with a price of $499. Currently priced at $530.
Intel is still King of the gaming CPU period. This has been proven many times by real world benchmarks. Check youtube there are a couple completely unbiased benchmarks on there.
Real world synthetic VS gaming benchmarks. Synthetic benchmarks are fine for testing but real world Gaming benchmarks paint a completely different picture between the brands. Ignore the Cinebench Rendering benchmarks. We know AMD chips are better rendering cpus.
The best Intel based Motherboards are still Way over priced. They have always been that way for some reason. My motherboard was the 2nd best AMD motherboard and it was $160. The Best AMD motherboard at the time was priced at $189. The best Intel motherboard at the time was almost $400. That is why I keep going back to AMD. Price VS Performance. If I had no budget I would definitely go with an Intel chip and Nvidia graphics.
