I am not a fan of 120mm AIOs, a gooda air cooler will give you the same result at less noise.
The dual 2080ti leads me to believe gaming only.
Any reason for the 9700k in particular?
Looking at Anandtechs benchmarks, the 3700x comes out on top in or very close (below 2%). Going with 3700x + X570 is going to save you a little money.
Also: Which country are you in? What budget do you have? This makes recommending parts easier.
The CPUs will perform the same, the GPUs will perform the same, the RAM will perform similarly (because Intel), the storage won’t be noticed for the most part.
With no information on what the computer is being used for go with what Discobot rolls I guess.
Doesnt account for overclocking, amp spikes and psu degredation. Particularly since running two GPU’s will put a fair amount of pressure on the psu rail (particularly if it si a single rail psu)
edit to add mild overclocks - comes out at nearly 1200w
Regardless, even with NVlink dual GPUs are like… pretty pointless considering the cash. I mean theres a couple games that are insane with 2 Titans but… why the 2 2080tis? Are you doing something besides gaming?
