Hi Nejc, thanks but yes it's too far for me to wait that long currently!
Do you have any recommendation on mobo or ram (how many dimms should i look for)? Thanks ! :)
I hear ya on the waiting part! :)
Sorry but I'm afraid I'm not quite that knowledgeable yet about the AM5 platform, anything I'd say about AM5 and memory would be pure speculation from me.
For motherboards, I typically go with the brand I trust the most and their most fitting product to my needs. I don't like overspending on stuff but I do like to be future proof at least somewhat so a couple of NVME slots, at least 2 PCI-E x16 slots, minimum of a 2.5GbE port... and that is mostly what I'd want myself.
I wouldn't worry about the overclocking feature set, I reckon you won't be doing that. Arguably the 7xxx series will do that for you anyway unless you're running in ECO mode.
Performance wise, please double check this but IIRC there isn't a difference between the B650 vs 670 or 670E chipsets. From my understanding the main difference is basically in the IO and extra other features.
Puget systems has a nice comparison on the topic of features between the chipsets:
https://www.pugetsystems.com/labs/articles/AMD-X670E-vs-X670-vs-B650E-vs-B650-2361/I guess if it were me I would probably start with picking the right chipset for my needs (including future proofing a bit). Then find a reputable brand and never opt for the absolute cheapest board (those might skimp on VRMs and things that might actually hold back the 7950x a bit - although I haven't double checked this for this gen but that is from my understanding where cost cutting can hit ya with these high end CPU, cheaper mobo combos) that has the extra features you find useful. Would watch / read a review as well.
Also, take the time to double check everything that was said above. Again, I'm not that in the know how about AM5 yet. I hope you got some good "aha, I shall google this" moment out of it though :)
