i would agree if OP was upgrading every year/other year as then could carry the ram forward, but a simple ddr4 build would provide the best value currentlyI can't see the point in doing a DDr4 build these days, you are saving little in the long run,
it is, but total system costs stay roughly similar if the parts are chosen correctlyand £630 is hella expensive for a 6800XT, you'd hope it would be 40% faster if you are paying 50%+ more for it.
at time of posting i've only gone for ocuk parts
as always, you and me will tell people to shop around for the best prices
