This is an excellent price for the 7900x if it fits your use cases. I've been running an undervolted 7900x in my primary system for 2 and a half years, and am quite satisfied with it. However, keep in mind that ram is extremely expensive currently, so if you don't urgently need a new system (within the next year or so) I'd recommend holding off.
The 7900x is a bit of a jack of all trades, being a decent gaming cpu and a decent multithreaded productivity cpu, but not truly exceptional at either. Looking at the specs on paper would make you think it should be significantly faster in gaming than the lower tier 6 and 8 core zen4 parts, but that's generally not the case. It has two 6-core ccds, each with 32mb of L3 cache, and suffers a substantial penalty in gaming performance due to cross ccd latency if cores from both ccds are used simultaneously.
In terms of raw gaming performance with ddr5 6000mt/s memory the 7900x is approximately: on par with 7700x, a bit faster than the 12900k, a bit faster than the 5800x3d, a bit slower than the 13/14700k (which kill themselves), a bit slower than the 9700x, on par with the 265k, substantially slower than the 7800x3d, and substantially slower than the 9800x3d. So not a slouch by any means, and more than sufficient if you aren't planning to run a rtx 5080 or stronger at 1080p, but not truly incredible performance either. That being said, if you're only a gamer, a 7/9700x (7/9600x also an option, but 6-cores is getting a bit long in the tooth) will get you similar or better performance at a potentially lower price (with a bundle), and an am5 x3d cpu will offer significantly better performance (in cpu bound scenarios) and better power efficiency, though at a higher cost.
In terms of raw multithreaded performance, the 7900x is once again middle of the road among productivity focused cpus. It absolutely demolishes all single ccd (8 core and below) amd cpus in all but a couple of very specific avx512 workloads, but single ccd cpus aren't aimed at multithreaded workloads. As a dual ccd cpu, it has additional infinity links, and therefore can achieve higher memory bandwidth than single ccd am5 cpus. With ddr5 6000mt/s memory the 7900x approximately: beats the 12900k, is slightly worse than the 13/14700k (which kill themselves), is substantially worse than the 13/14900k (which kill themselves even faster, and are much more expensive), is moderately worse than the 265k, is substantially worse than the 285k, is substantially worse than the 7/9950x. It's the best value option for moderate multithreaded workloads on the am5 platform, being far cheaper than the 9900x and 7/9950x. In terms of value it falls a bit behind the intel 265k, though that has the disadvantage of being on the dead end lga1851 platform, as opposed to the am5 platform which is rumored to receive another two generations of slot in upgrades (at least 1 generation guaranteed).
In terms of efficiency, the 7900x is once again middle of the road. It's far more power efficient than intel's 12-14th gen cpus, but not compared to current gen arrow lake. Zen 5 is a moderate step up in efficiency, though with appropriate power limits the 7900x is still fairly efficient under load (I recommend using amds 105w eco mode, which has a minor performance loss for substantial efficiency gains under full load). As a dual ccd chiplet based cpu, idle power usage is quite high, though this can be mitigated to a large extent by decreasing soc voltage which will generally be set quite aggressively by the motherboard to assure memory controller stability (only do this if you know how to properly stress test, I recommend y-cruncher vt3 as a good baseline test). If you're using a discrete gpu, disabling the igpu in bios should give you some extra headroom to lower vsoc.
The 7900x has meaningful scaling with memory up until 6000mt/s (the sweet spot) due to the way it's memory subsytem works, don't use slower memory than 6000 or you'll be downclocking both your memory controller and infinity fabric if you want to maintain even partial sync. Depending on your luck with the silicon lottery, ddr5 6200 (common), 6400 (semi-rare), and 6600mt/s (very rare) may be possible in 1:1 mode (uclk=mclk) while maintaining fclk at an 2/3 ratio (eg. ddr5 6000 fclk:mclk:uclk 2000:3000:3000, don't forget ddr is double data rate so 6000mt/s is 3000mhz). This will allow better performance, but will substantially increase idle power draw due to memory controller clock scaling with soc voltage. Performance of 6800mt/s through 7400mt/s will actually be slower than the lower speed 1:1 configs. Running ddr5 7200 and up in 2:1 mode can be faster (particularly ddr5 8000), but can be extremely finicky depending on your motherboard and your silicon lottery with the imc and phy. Ram using hynix memory chips has substantially better overclocking and tuning potential than those using samsung or micron, however with the current ram apocalypse pricing for hynix ram is obscene. Anything ddr5 6000 cl38 or better should realisitcally be enough if you don't plan on manually tuning your memory.
Amd's "curve optimizer" feature allows you to adjust the v/f curve of your cpu, by using a negative offset you basically tell your cpu to use a lower voltage for a given clockspeed for lowered power draw, better thermals, and improved performance (assuming you set it correctly). I highly recommend using this feature if you're willing to stress test your system. A negative curve optimizer offset can NOT damage your cpu or motherboard, however if set too aggressively it can result in lowered performance due to clock stretching (lower effective clocks as a hedge against instability with a too aggressive undervolt), and/or instability (which could result in corruption of your os and files). I highly recommend setting your offsets individually per core, the differences between cores can be quite massive. The common recommendations you'll see online about setting -15, -20, or even -30 all core for zen4 are complete bs for most cpus, most of those people have at least partially unstable systems and just don't realize it. My 7900x has one core I can reliably get to throw an error at only -7 using the right stress tests, while some others go over -30 without a problem. I've found that on my 7900x bursting single core ultra-heavy avx2 workloads is by far the best for finding edge case instability. I personally recommend using corecycler with prime95, avx2, auto runtime, fft size 4k-240k as a good baseline check.
Overall, if you don't live near a microcenter, want a cpu that's decent for both productivity and gaming, and want the platform longevity of am5, this is a good deal.
Sorry for the massive wall of text, I couldn't sleep, saw this deal post, and just started (literally) autistically rambling. Hopefully this is helpful for someone.

the only reason to get the X version is if you running a A serious board where you cannot change power profiles in BIOS, so you cannot run a 7900 with 170W profile. (but i think you could run 7900X in 65 W profile using ryzen master app even if you running A series board)
