is it a good idea that if i buy rtx 2080ti with 4770k, for 4k ? any benchmark which directly compare with the modern cpus ?? i want to wait caz i want to buy a zen 2 cpu not the 9900k.. but i cant wait for the 2080ti..
For 4k no problem 1080p your cpu will bottleneck system. My 4790k and 2080 are fine at 1440p and 4k lose about 10% of gpu power at 1080p due to cpu. Hope that helps.
If RTX (ray-tracing and AI) is enabled at 720p or 1080p on games or at any resolution screen on softwares rendering, your CPU doesn't bottleneck GPU.
