I already have the 1070 and want to re-use it as it is perfectly good for 1080p and 1440p gaming.The RTX2060 is allegedly less expensive, and, matches or slightly exceeds (depending on the game) a GTX1070 Ti...
(I see some RXT2060 variants at Newegg for $389...)
Because of my budget, I thought it was a smart option to get some fast storage know, and then get more storage later. I won't be downloading many games or applications anyway.i reccomend to buy more storge. you can buy a 1 or 2tb hdd. they are relatively cheaper than ssd. you can use ssd storage for your operating system and programs as ssd are faster ane use hdd for storing other files.
