I'm still not sure about going with socket 2066 but I need to upgrade and I haven't seen good things from AMD for a while now other than they have a lot of lanes available and don't lock it down...


I'll be running 2 video cards: 1080 GTX Gaming X 8 GB DDR5 for a primary 28" 4k monitor, and a 750 TI 2GB DDR4/5? for 3 more monitors at 1080p each. I have 1 more monitor hung, and I may go up to 6...

I am planning on going with 32 or 64 gb memory minimum for this build with space to upgrade to 128 ( which would probably cut out the 6 core - also the 8 core is $100 more so that may knock it out too )..

I know the 2 cards will run at 16x and 8x which leaves me with 4 lanes for a single m2 drive ( or are lanes taken for Sata connectors - 1 per 10? )

The PC will be used for everything from streaming 4k to gaming 4k, to virtual reality when I get a headset ( when one which is true 4k comes out ), 3D printing, designing, programming, and much much more. A lot of which will be open at the same time. plus a browser with hundreds of tabs, or more than one browser opened at any given time...

For gaming I know I'll need speed, not so much cores beyond 4 - base clock for the 8 core is 3.6 but turbo 2 is 4.5... the 10 core is 3.3 at 4.5 with turbo 2... What are these turbo speeds? Are they manual overclock speeds, or does the cpu cycle automatically? But with most of the other work I do, more cores are better...

I'm a bit of in the air, I don't mind spending $900 for the 10 core 20 thread processor and the 48 lanes option is nice - but I need to understand lanes more before I pick - which is where you all come in... The 8 core 16 thread processor is only $450 right now but only has 28 lanes leaving me with 0 if I use an m2 drive ( and I do want to upgrade from my SSD soon as the SSD I have is more for gaming or so as the speeds aren't great, but the bottleneck could be from my current pc configuration )....


Any help you can provide would be fantastic - thanks.

How urgent is your decision?

New chipsets from Intel are due our soon, probably July.
It is rumored to include support for a 8 core processor and additional lanes.

If you must buy today, I think a 8700K processor might be your best bet for gaming.
Most will clock at 5.0 or better for all cores.

One issue to think about is how much you really need more than 64gb of ram.
Current Z370 motherboards top out support at 64gb.

The capability of more than 64gb might sound nice, but adding to a current ram kit will not be supported and might not work.
Ram must be matched.
It is best to plan on buying what you eventually might need up front or plan on selling the old ram whenever you do upgrade.
Considering the current high ram prices, See if you can't make do with "only" 64gb.
Look at your current usage and see how you might do.
As an experiment, reduce the ram available and see how sensitive your workload is to a lesser amount of ram.
I am betting that it is not much.
Understand the task manager ram statistics.
Windows keeps little used code in ram in anticipation of possible reuse.
Your key is the hard fault page rate.
If it is anything significant, it indicates a shortage of ram.

On the ssd, look for one of the new pcie nvme devices. Probably Samsung 970. It has a nice low single queue latency.
Sequential speeds are what the advertisers like, but it is not usually a big factor in performance.

With your apparent budget, I would go ahead and buy a GTX1080ti for gaming if you want to buy today.
Adding a couple of side monitors to the main gaming card will have no impact on gaming.

I'm looking at socket 2066, not 1150 or 1151 - was this response meant for someone else? I also have a lot running at any given time - with 8GB memory I have now and what I've been running for 10 years there are significant slowdowns.

I really don't want to go with 1150 or 1151 because of the lack of cores and lanes ( limited to 16 ) despite the fact they top out at higher speeds.

I already have a 1080 GTX Gaming X, and a 750 TI.


What I need to purchase is Processor, Motherboard and Memory. I may add an M2 drive too. I wanted to know how the lanes work on the processor and x299 chipset - I may consider AMD but I haven't seen much I like about them recently and have read a lot of complaints.. Also, from personal experience I've watched them degrade which is why I purchased the current pc of mine 10 years ago...


Adding additional monitors has a massive impact on gaming. When I was only gaming at 1080p and not 4k, if I ran with 1 monitor I would get substantially higher FPS than I did when I ran two monitors despite one monitor only showing the desktop... This is why I use the 750 ti - so it runs all secondary monitors ( I have 5 in front of me and something to hang a 6th but only 4 are active right now )...

I guess I'll organize the questions below so it's easier to follow - also, I would prefer to buy now but I don't have trouble waiting a few months - it has been, afterall, 10 years...

64GB memory is the max for the 6 core processor, so I doubt I'll choose that.. so I'm left with the 8 core or 10 core or something else suggested here..

Help me choose my next processor: 2066 :: or 7800X 6/12 28 -- 7820X 8/16 28 lanes -- 7900X 10/20 44

I'm still not sure about going with socket 2066 but I need to upgrade and I haven't seen good things from AMD for a while now other than they have a lot of lanes available and don't lock it down... Opinions?

How do the lanes on the processor work? I know the 2 cards will run at 16x and 8x which leaves me with 4 lanes for a single m2 drive ( or are lanes taken for Sata connectors - 1 per 10? ).... Is this accurate? Specifically how do they work, how are they divided between equipment and which equipment uses them?

I see details of Turbo technology on socket 2066 processors by Intel - what does it mean? Are they manual overclock speeds, or does the cpu cycle the speed automatically on a core to core basis or overall?

My budget is open - the $900 I listed was regarding the processor only - I don't mind spending that much for the processor itself but I need answers to my previous questions too help me decide whether or not the extra lanes are worth it - I could always buy the 8 core 16 thread processor and upgrade later.... I know that I will be spending $300 to $400 on 32GB memory - and I'm ok with doubling that for 64GB... Overall, I am ok with spending close to $2000 for the motherboard, memory and processor - but that doesn't necessarily mean I will... I just want to know my options and other users experiences..

Thanks.

No offense, but, did you perhaps stop reading any and all tech/computer related websites as of about February... of last year...?

An R7-2700X/B450 motherboard offers incredible content creation value for the $400 spent on CPU/MB...; assuming you are interested in content creation/video production/editing, given even mentioning socket 2066 CPUs, as they are somewhat goofy a choice for... well, anything else....

4k gameplaying does as well on a $190 cpu as it does on a $1800 cpu...

Choose carefully.

(The desire to stream and game would make an R7- 2700X seem quite logical....8 cores/16 threads....)

PCI-e lanes are not an issue with AM4 boards...

It's been around 7 years since my accident ( may 7 2011 ) which left me with a broken neck, back and severe nerve damage... Since then I'm limited to a 40 hour work week of time I can spend on being 'productive' or otherwise per 3 month period if I'm lucky, otherwise it can take upwards of to 6 months to a year... It's a hell I wouldn't wish on anyone; I'll be asking the court for the right to die when I go to trial against the person that did this to me.

I've tried to keep up to date as much as possible, but with such limited time, it hasn't been easy... Some days are better than others but all days are hell...

A lot of the reading I did on AMD stated AMD was still running hot - however this doesn't seem to be the case... AMD is soldering chips to the lid and intel is using crap-goo in $2000 processors which is a shame... I looked at some benchmarks, and it seems like Intel still pulls ahead in many of them...

Although from what I've also read - AMD puts more lanes on their cpus but don't have the chipset lanes or something along those lines making the lanes comparable to both manufacturers - but I need to confirm this for myself...
