with my system now running a 3070 i only have a i5 8000 and b360 asus tug gaming board

i think i would like to upgrade to a intel i9 9900 unlocked? 1151 socket with a z390 board?

thoughts without going to intel 10 gen or new sockets.. want to be as streamlined as possible as this would be my first time replacing the board and such .

Thoughts?

What are you looking to achieve with the 'upgrade'?

You could keep the board and upgrade to a 9900 K or non-K (probably best suited to a non-K) and get the core/thread bump, just no 'unlocked' or Z board features (overclocking, higher RAM speeds etc).

looking to rid some of the loading issues from scenes.. minor screen tearing.. cpu usage with NO other programs being used is getting high in percentages.. like pga 2k game it will stutter sometimes mid scene.. running aw DW 3420 monitor (btw i HATE this monitor) call of duty will get some minor screen tearing also and cpu usage is high makes me think its undersized i have read a lot of people notice a TON of difference upgrading to a 5ghz chip .. also running h100 corsair cooler and 32 gb ram 3200

I don't think a CPU upgrade is going to improve that experience specifically.

Depends. Doing the same thing(s), you'd benefit more from the core count bump than the clock speed 100% of a 6core/6thread CPU is only ~38% of an 8core/16thread chip afterall.

Since you have a cooler already, a 9900K/KF would net you a little bit in clock speeds over the non-K.

If you could find a Z390 for a reasonable price and recoup most of the cost selling the B360, I'd consider it. I'd fully expect the Z390 will cost a fair bit more though.

my budget is around $600 for a new cpu and mobo at this point.. also running a 650 watt corsair PSU. just want to maxmize what this system can do for the next year... getting into graphics and movie making soon also.. I am concerned about bios issues though as ive never done that .. asus seems to have a favorable bios so i was thinking of going with their z390 board

you feel thats a good start?

Honestly, no... Not particularly.

You could have a 9900, 9900K or 9900KF for ~$380:

The added cost of Z930 doesn't strike me as 'worth it' for ~$600 all in.

This is a bit of a flaw. Replacing the board is not 'streamlined' by definition. Boxing yourself into only the same era under the guise of simplicity doesn't really work here.


With $600 (and before considering new 11th 'gen' chips), an i9-10850K and Z490 would probably be a better buy, and no more 'difficult' in execution vs what you're proposing already.

10 core / 20 thread, 5.2GHz boost - it's a 100MHz clock drop over a 10900K and otherwise the same. +2core/4thread over the 9900K, a bit more 'modern' (you can drop 11th Gen chips into a Z490 but not a Z390) and very similar money.

Agreed on the ASUS BIOS. I find it more user friendly. I wouldn't spend substantially more for an ASUS board of MSI or Gigabyte etc, but at a similar pricepoint, I'd lean more towards ASUS.

i had the 34inch MSi 144 hz monitor and it was not g sync so then i bought the alienware at 120 hz.. the color difference is insane.. i HATE the alienware compared to the msi.. i think im going just buy the lg 850 instead that has gsync plus the high 144 and higher color ratings... some games on my alienware look so bright like sun rays and ive tried tweaking it but man i just hate it for some reason.

i think probably because i cant find a combo around $600 that i wanted to stay at unless you think otherwise? i guess that difference would be huge

lot of good info here.. so now im going to start looking into 400 series boards with a 10th gen intel chip.
am i at the point where the corsair h100 would NOT be sufficient on this? do i need to go to some extra water cool setup instead?

If I had a $600 budget for CPU/MOBO, I would go with the newest motherboard socket from either Intel or AMD and corresponding CPU. Not sure why you would want to go with a new, dead-end platfrom such at the intel 9th gen board. 10th gen Intel or X570 Ryzen would be my choices. Otherwise, I would just stick with the board you have and upgrade the CPU sans overclocking.

Agreed. ^

I went from a 4c/8t 7700k to the 10900k and while it did give a solid clock speed bump the core count bump is really noticeable when doing things like video encoding. It also makes for a much smoother 4k framerate in MSFS2020 and similar.

With 11th gen coming you can get a 10th gen setup for a better price too. As others have said that's what I'd consider. As far as the 10850k vs the 10900k you need to consider overclocking... from what I've read the 10850k doesn't OC as well. Something to consider if you want to push the chip... as I did.
