Mainly for CPU or GPU rendering?
What i can say at first sight... a Xeon is not needed, normally overpriced and outdated. And 16GB RAM is definitively not enough. Without knowing the components, it's impossible to say much about this config. But i suppose that at this price everything besides the GPU is more on the cheaper side and the GPU is the most expensive part here.
Video cards are still very rare and absurdly expensive atm.. So if you're planning more for CPU rendering, a smaller card than a 3080 TI could be a better choice. There has been announced a 3070 TI with supposedly 16GB for the next months.

On the other hand it's still possible that the offer isn't that bad, if this is a PC from a bigger manufacturer like Dell or HP and they are still getting GPUs at a lower price. But to say anything about it, we need to know the parts.
Here is a config that i would choose at the moment in this price range (for CPU rendering):
Ryzen 9 5950x - 64GB - 500GB+2TB SSD - RTX 3060 12GB

and the same with 3080 TI
Ryzen 9 5950x - 64GB - 500GB+2TB SSD - RTX 3080 TI 12GB

Both configurations with 16 cores, 64GB RAM, only SSDs (no mechanical drive), decent board and good CPU cooler, PSU and case. The only difference is the GPU.
(Not totally sure regarding the board, i would have to look deeper into it. But at least this one comes with 2x PCIe 4.0 16x (for potential GPU rendering upgrades in the future) and 2x M.2 PCIe 4.0 4x for a second fast M.2 SSD.)
For more CPU cores you would need to switch to Ryzen Threadripper, where everything is much more expensive.
