i want to but a card for minning to test but i dont know what is the best for both XMR and ETH ...
1- GTX1080Ti
2- ASUS R9 295X2
can anyone explain which of them better and why ? and how to know and make a compare between cards ??
Compare the cards in GPU boss website. Google "GTX 1080 ti vs ASUS R9 295X2 gpu boss" and you will have your answer. But let me answer you first go for the 1080 ti as it is much less power hungry and you will save a lot of energy. A 1080 ti is usually up to 250 watt or a bit more while R9295X2 is at least 500 watt. Both are good for both XMR and ETH so go for the GTX 1080 ti.
