Yes it was, I got it for $321.... It's awesome, I am sorry you missed it..
I wish I could advise better, but I went from 1080p60hz to 1440p165hz so I can't really comment on which is better.... This is all opinion and based on info I found when I was depating 4k60hz vs 1440p120+. If you are really serious about FPS then the higher refresh is probably better. I play bf1 and battlefront and it made a noticeable difference there.. I turn the settings down as low as I need to to get to 120fps.. But the 1440p is amazing for any single player game. If you are more relaxed about your FPS games then I would go for higher res, but if you are more serious I would go for higher refresh.
