good morning il start with my current pc specs just to be informative: i7 7700 Asus H270 strix 16GB 2800Mhz 1070GTX ( i plan to switch for 6700XT, playing on 1080P\60hz) 1 x 2TB regular HDD for general use ( including gaming, i know im late to the party ) 1 x 120GB old SSD for OS i am planning to buy a new GPU ( best price i will find ), and upgrade my PC with a new SSD. browsing online on these issues including in our forum raised some questions on my part, so il be glad for some helpful comments. my most demanding usage is gaming. mostly single player gaming, with the new d2 resurrected in mind. the other usage is working on excel, internet, music.. and that's mostly it. *price is not a main factor here, considering the difference that i saw between NVME and SATA. 1. reliability issues - NVME or SATA ssd ? 2. should i split the OS and my Steam\gaming libraries to two different SSD's or just buy a one big SSD ? thank you.
