Is it worth to upgrade to a 10900k from 3700x SMT OFF - for input delay purposes? My system on 240hz(v-sync, g-sync on, capped at 237 fps) feels like a brick. Everything is delayed, microstutters.. my brother is on 9900k on 144hz and just by looks its looks very responsive and snappier :-/

If you have the money for it then I would say yes. Your mobo and ram are also important. The Apex is a top quality board but might be too costly, generally for max memory oc potential you want 2 dimm boards. ITX boards like Unify and Aorus Ultra ITX are decent budget alternative.

3600mhz 16-16-16-36 isnt bad, but for an 10900k I would suggest 4400mhz cl19 , the patriot viper steel are solid sticks. Also if your current sticks are b-die then you might keep it and oc it @CR1. Also consider investing into a ram cooler, they should cost around 10-20$ and can easily help you push your memory oc further due to lower temps. This is a good ram cooler at that price.

A very overlooked part when buying hardware is the psu, my knowledge on psu is limited. But titanium or platinum rated 800w (or+) should be good enough. Also if you're going all out on input delay 5700xt might be worth looking into, the general consensus that (non-vega) amd gpus are snappier than nvidia gpus. You can also adjust the vram timings on 5700xt which you cannot do on 10th or 20th series nvidia cards.

Having airflow over dimms will improve temperatures regardless, but if you want to see full benefit you will have to remove the heatspreaders. You can use a hairdryer or w/e, but if you're playing with 100-200$+ dimms you should use the ln2 method. If you're hesitant to bother will all of this "just" for better memory performance, remember that memory latency is the most important bottleneck in computing and that temperature has a massive impact on memory performance.

For power supplies consider more than merely wattage. A bad power supply will ruin system performance and stability, check out this little compendium.

No need for RAM cooling gizmos, IMO, just rest a 140mm fan on the GPU and point it towards the RAM? Welp the orientation of my game rig places the MB on the right side, 800D case

Out of curiosity, why do you think a 15 dollar ram cooler isn't worth it? Is it because you don't think temperature matters that much, or because you think some random 140mm fan is "good enough"?

1.48v on my B die keep it under 40c with a 140mm fan, ambient of ~ 85*f, while stress testing 15gb worth of my 16gb, 10 runs tm5.

The fan also can serve to cool the CPU heat sink.

Gaming the ram runs around 32*c same ambient. EDIT: my bad, 33-34*C

EDIT: I can check again for you. It might be lower when stress testing.

Thank you for your answer! The fricking 10900k is not available in my country, so I want to buy the 10700k. Whats your opinion about that?

That doesn't answer my question. Ram scales with temperature alot lower than 32c.

10700k is fine, check pricing on the 10700kf aswell. For motherboards, after apex your best options will be z490i unify and aorus ultra.

Keep in mind both these cooler on the video are 3.5k rmp and the one I linked is 4k rmp so it should be better. At 15$ I really don't see why a ram cooler wouldn't be worth it. With those temp decrease you could probably shave off 1-2 whole ns of memory latency, which is pretty huge.

Edit: Full disclosure, I am not affiliated nor do I profit in any way from the cooler I linked, its the best I could find in that price range. If you find something better feel free to buy that as well as share it here.

Pretty good processor. KF usually are lower priced and oc better, so check for that one. However in some countries KF maybe more expensive than K , in which case I'd probably go for the cheaper of the 2. Also for 10700k/kf Unify or Aorus Ultra ITX should be fine, you can also go Apex if you really have lots of money to spare.
