So I'm new to water cooling and I want to start a custom loop with my i5, r9 280x toxic, and maybe another future GPU. I'd use a dual radiator and id have to find other good parts. My questions are if there's a waterblock for my GPU. The ones I've seen for others have been over 100$. Is that how much a water block costs? What will my final price approximately be for the whole loop? And if its over 150 it doesn't seem very good for price to performance but any thoughts and tips are welcome thanks in advance!
