ALL DDR memory is measured in MT/s, which is Megatransfers per second. Since modern memory is DDR, double data rate, Mhz was no longer an accurate method of measurement for DDR SDRAM unlike it was for standard SDRAM.
For your CPU, and all Ryzen 5000 series CPUs, there is little point in going beyond 3600MT/s because once you do there is an infinity fabric penalty to be paid once you lose the 1:1 ratio which makes it lose all value in most cases unless you can get a VERY high speed kit to work, which is both very expensive and very unlikely for most board, memory kit, CPU combos. 3600MT/s is the sweet spot for Zen 3 platforms. Some will tell you to get a four rank configuration using four DIMMs, but the problem with that is that hardly any Ryzen systems, at all, will support the full high speed memory kits with all four DIMM locations populated. IMO you are much better off going with two 3600MT/s low latency DIMMs and IF you can them with two ranks per DIMM you can still meet that recommendation but in reality it isn't all THAT important. We're talking very small percentages of improvement.
And you SURE as heck don't want to buy two individual 32GB DIMMs, or two separate 2 x32GB kits. You want to buy ALL of the memory in ONE SINGLE KIT otherwise you are very much rolling the dice on the idea that they will play nice together which MUCH of the time these days with high speed kits they will not. Especially since many of these kits aren't even made up of the same composition from one production run to the next. Many if not all of these manufacturers may simply use whatever they have on hand that will still meet the requirements for overall throughput and latency even if it means using entirely different ICs (Memory chips), or totally different rank and row configurations.
There is a much more detailed explanation here:

Which, you can still GREATLY improve your performance IF you get a 3600MT/s kit with a very low latency. But they are expensive.
How much are you willing to pay to gain maybe 10% performance over what you have now?
And when it comes to the capacity, are you sure you even have a NEED for more memory? Because for 95% of users out there, 32GB is more than they will ever use unless you are also running substantial VMs, or very high end applications, or some combination of all those things plus very memory greedy games with a ton of mods and overlays installed AND/OR are also needing additional memory for recording operations while doing any or all of these things. Do you KNOW you are in need of more memory or does it just seem like a good idea because it's commonly thought that more is better?
The fact is, even not counting the infinity fabric penalty, you wouldn't gain much by going with a 4600MT/s CL19 memory kit over your 3200MT/s CL16 kit, Your kit has a true latency of 10ns. The kit you are looking at would have a true latency of 8.26, but that is ONLY IF you didn't have a latency penalty to pay because of exceeding the 1:1 threshold of the infinity fabric. By the time you factor that in you are probably looking at more like an 11ns true latency and it simply would be slower than what you have now when all is said and done.
Now, if you could find a 3600MT/S CL14 kit, you'd have an 8.75ns true latency and you would not have a penalty to pay, so it would definitely FEEL much snappier in memory intensive operations but even so, the overall performance gains probably wouldn't be all that enormous for the cost, IF you could even find them anymore which is proving to be nearly impossible if you want to buy them new because most manufacturers have moved the majority of new production to DDR5 and whatever DDR4 they are still manufacturing are the mainstream kits that will appeal to the largest number of users. Plus you have to also factor in that all of the Ryzen platforms are very picky about what memory kits it wants to play nice with and mostly that's on a per-motherboard-model basis for the most part, with the specific CPU model SOMETIMES also factoring in. Mostly though, it's the board.
And I'm not seeing ANY 3200MT/s CL14 2 x32GB kits that show as compatible for your motherboard, not even from G.Skill, so while there are a couple of kits still available that fit that description they are like 200 bucks for the kit AND you would be rolling the dice that they will play nice with your configuration. And it probably would because basically all of the 3000MT/S and 3200MT/s CL14 kits are Samsung B-die IC kits, and those generally almost always work with Ryzen platforms but again, it's not cheap, and there is some risk involved.
i am planing on moving to a Linux OS fulltime and run a windows vm in the future at some point. main reason ive been looking into upgrading my ram is from games hogging so much but maybe it would be better to just hold off and wait til i absolutely have to or i do a whole new build and on DDR5
