I have a 4K 60hz display and I plan on using ray tracing when available. at the highest resolution possible. I'm thinking a 9400f should be just fine. I bought one off amazon for $140. Thought it was a good deal. Bought a cheap B360 motherboard for $40. I couldn't afford much because of buying the RTX 2080 ti. I'd like to have a better CPU but it's really not necessary is it? For just gaming at 60hz at probably less than 60 fps with ray tracing on. I'll probably play 1440p with ray tracing on. Well anyway the parts will be in on Tuesday. Can't wait.
