Part Recommendations

[TwinTurboRYZEN_PLUS-ULTRA]

I'm in the middle of picking out parts for my next build and I'm getting stuck on this question and other memory questions.

I've pretty much settled on the MSI x670 Tomahawk wifi motherboard.

I have a brand new 1000W PSU and I'm going nice air cooler this time vs the AIO since I think I don't want to risk putting in my older, years old used AIO into the new system just to have it fail or possibly leak.

I'm stuck on the type of RAM and Ryzen CPU.  Do I just go with the 7800X3D or the 7900X?  Which one has a better memory controller and what timing should I be looking at?  

I have an RTX 4070 already so thats coming from the older system.

I use HOTAS as well as an XBOX controller to game.

Someone help a brother out

For most stable memory controller, you choose Ryzen 7800X3D. It has more good stability for memory and is very nice for gaming. Use DDR5 RAM speed about 6000MHz, with timings CL30 or better. Your air cooler good pick compared to older AIO. Your RTX 4070 will pair well with either CPU.

What would you go with between these two RAM kits?

The T-Create has a bit higher timings but they also have a lifetime warranty.  I wish I understood CAS timings better but I just can't wrap my head around it (hence why I'm asking for advice)

Lifetime for me is maybe 10 years max with PC so it isn't too big of a deal, just a nice bonus.

Both are RBG FREE & LOW PROFILE (I think the low profile is a must esp with the Peerless Assassin 120mm air cooler)

I really don't care for RGB.  Last build I had a theme and made it look like Rasputin from Destiny with black/red color effects, but this go round I just care about performance to cost, stability and lots of PCIe slots for HOTAS, m.2 as well as HOTAS/controllers.

Thanks again for any advice

What is the intended use? If you need the extra cores of the 7900X go for that. If used primarily for gaming go for the 7800X3D.

Here's the QVL memory list for your motherboard

I've had great results with G.Skill memory, they also have a lifetime warranty btw.

When it comes to memory timings, lower is better. You aren't going to "feel" the difference between CL30 and CL34 at the same speed, but if the price is comparable why not go for the lower latency?

Well, I'm a bit torn between what I'm currently doing vs what I plan on doing.  I mainly watch videos, mess around with simple audio production and game.  I was considering learning how to 3D model so I wonder if the extra cores would make that huge of a difference.

I really don't need onboard graphics but it would be a nice convenience to have just incase my rtx4070 bites the big one.

I'm not interested in extreme overclocking to get a few frames more but if the prices are in the same ballpark then I suppose it would come down to how many cores programs actually use these days.

It's been awhile since my last upgrade but, I've always heard most programs usually don't even use all cores on a quad core CPU.  If 3D modelling would take advantage of extra cores and its within 50 bucks of each other I would probably go with the extra cores. 

I've heard the only games that seem to use extra cores are simulation games like City Skylines, or ANNO 1800. 

I haven't really dug deep into 3D modelling requirements so I'm more thinking of future proofing (or slightly extending 😉

I did notice one processor uses 120W vs 170W.  I just don't want to regret a purchase down the line but I suppose no matter what I choose there will be some regret.  50 Watts is a lot of extra power and heat to dissipate though.

Sorry but I've done made things more complicated....
