It depends on what the 6 cores are. Like I have a 8C/8T dedicated server sitting in my closet that costs $65 per the number of times you buy it. (Usually once.) The cores are not as fast as the highest-end Epyc cores, however ;)
At the $65/month level for an OVH dedicated server, you get a 6-core CPU from 2018 and a 500Mbps public network limit. Doesnt even seem like that good a deal.
There is also a $63/month option that is significantly worse.
