asrock H81 costs new in shop 83$ used MSI Z97gaming 5 costs 105$ so do the math, besides when i want to resell it later it will be much easier.
You misunderstand what I said. People that run Asrock h81 pro btc don't put a multiplier on. They just run with 6 gpus.
People that use multipliers use cheaper mobos.
Also I didn't realize you were in Poland. I know your costs are a little bit higher than mine in the states.
