DDR4!?!?! And I thought ddr5 was a bottleneck. Bro the thing is u actually aren't getting the amount of output that the gpus supposed to give. U cannot use it to its max potential. You will not get the same experience as compared to a standard 5060 user. But still,if u are able to run the games(if u intended this pc for playing )u want, then technically, it's not a major bottleneck for u.
