So... I plan on getting myself an RTX 2080 for about 750€. For example the Gigabyte 3 fan custom design. Now while doing my research I figured, that I also could get myself the cheapest 2080 on the market for 650€, install the NZXT G12 and a 120mm radiator on it, automatically OC it and call it a day. This would turn out to be about 750€ as well. The idea obviously being, that I'd get better performance for the same price... Any recommendations?
