Thanks for your Replies,
great Idea, I'll do that. Do you have any CPU-Cooler recommendations? The Standard AMD Cooler shouldn't be that good also I have 0 experience with water cooling ?
And yes. I forgot I have 2 more RAM Slots available so I'm just gonna buy 2 more of the same Sticks, like you recommended.
for the GPU, I think I'll go with an RTX 2070 SUPER like ZeouLs recommended.
Thanks again
