Before you purchase an ips monitor, may want to check out the technologies.

Oh god don't buy TN if you care about things other than CS:GO
have you seen a TN panel IRL? Absolutely disgusting. The 144hz IPS will be better. Same responsiveness without looking like crap.
AAA games are simply too demanding on highest details, even the king of all GPUs won't hit 144fps - but a 970 certainly will on less demanding games, like CS:GO for example. It's mostly useful for competitive gaming more than anything, and is actually a negative for Fallout 4 due to engine limitations. I personally would avoid it because you'd become spoiled by a higher frame rate and disappointed when it isn't able to hit 144fps, just like I and many others are with 60fps.
TN is better if you're a cheapskate, but IPS panels match TN panels nowadays. Almost every one will have 5ms response or lower. Your colors and viewing angle will be totally screwed if you go with TN panel.
I've decided on a different monitor, after learning TN is more suited to gaming.
This seems like a good deal. Although I want to make sure that site is legit instead of a scam, and the fact that it is refurbished isn't an issue. At that price it seems like a steal.
