i don't go by reviews. never have, never will....Yeah but in this case you know exactly what you are getting from reading all the reviews, you know performance isn't that good and that it runs hot, sucks up a lot of power etc. the decent thing to do would be just return it without opening if you're intent on going with Intel.
DSR is more for cases where you're misled over a product, like buying a GPU advertised as silent that turns out to make a racket (real life story).
as i said
i would understand if shoping online was like walking in a shop and able to look the product working and try it yourself before buying then yes you'll know if it's right for u or not
