How much is 8 cores in dollars?

Could you possibly clarify for me the cost of a processor with 8 cores, expressed in dollars? I'm attempting to budget for a new computer system and want to ensure I have a sufficient amount allocated for the hardware. Could you also provide any insight into whether the price might vary depending on the brand or any specific features that might affect the cost? Additionally, is there a general range of prices that I should be expecting, or does the cost fluctuate significantly? Thank you for your assistance in this matter.
