I currently have a gaming rig for gaming on a 3440×1440p monitor. I have an EVGA RTX 2070 XC Gaming, and an it 6600k with an ASUS z170i Pro Gaming Motherboard. Along with 16gb of DDR4 Ram, Corsair RM750x PSU, 500gb Samsung SSD, in a Corsair 250D. Is my current CPU bottlenecking the system I have, specifically with the RTX 2070? I haven't overclocked either. And if so, should I be looking at replacing the CPU and motherboard to the new 9th Gen chipset? If I should, should it be the i5 9600k or i7 9700k, as well as any recommendations for motherboards? I'm looking to mostly game at 3440x1440p, and do some 3D CADing.
