Ahhhh I’m confusing when I talk about them because I pluralize them too! My favorite pair is the 560s, or pluralized, the 560s…s. I found the 560s pair on sale back when I was on Reddit at /buildapcsales/ like a month after I bought a pair of 599 (actually 599 SE) and fell in love with them.
I looked it up and actually got the 560s for a STEAL at 160USD, so I think anything below 200 is a good deal.
