buying a new prebuilt PC from Ebuyer and im confused with the performance!

Burning_Sphinx · December 16, 2019

as the title says, im looking to get a new pre built PC and this is the best priced PC i found. (sry, i'm not gonna build it myself, too much hassle and i don't have the time).

that's the one i want to get, it has bench marks in games showing already which is confusing me because another (more expensive PC) which i will link now,

This PC is a 2060 super, so the 208 should blow this computer out of the water? i know it has a better CPU but in youtube performance comparisons that CPU only has like 10fps increase compared to the 2700x in most of the games i saw. im trying to do my research and im finding it very hard because alot of youtube videos im finding are showing me very contradicting messages, for example, the first PC has 1x16gb RAM, youtube videos such as this one...

that guy is saying that dual channel ram setups give an increase of 40% fps, and other videos i found when comparing single to dual channel ram says the fps increase is negligible.

I am a PC gamer, im not too well versed in technology, i recently wanted to get a new pc since my current one is aging and tbh this is all confusing me lol. if someone can help me out i'd appreciate it.

Also will 1x16 GB ram bottle neck a rtx 2080? is the cpu that it has (amd 2700x) bottlenecking the card?

how is 2060 super comparable and even getting more fps then a 2080?
