Default 2nd Gen 2K displays

In Amazon, The new Qnix QX2710 Evolution II is advertised to have 6ms response time which is close to the Asus PB's lag time of 5 mili seconds, and an improvement over last year model's 8ms, all while selling for $390. The Asus PB's price has gone down to $500.

Now in Newegg the same QX2710 is advertised to have 4ms response time and it's selling for $435.

There are two cheaper versions of the same monitor, one without pixel warranty on delivery, and the other with neither warranty nor display port. I completely ignored them.

So let me pick your brains out please;

1) which site is true? Does it even matter between 4 to 6 mili freakin seconds?

2) Should I just splash $500 on the Asus? It is a much older model (almost 2 years?) but the extras it will have are the OSD and that awesome stand. Bear in mind that neither are a priority. First priority is image quality, second is response time, third is price, fourth is stand, fifth is OSD.

Don't get stingy with your knowledge if you have experience with this stuff!

This is a pretty good site to start. Blur Busters | Everything Better Than 60Hz ? including 120Hz, 144Hz, 240Hz, LightBoost, ULMB, Turbo240, G-SYNC, and more.
A lot of the 2560x1440 panels can be overclocked, however this is not guaranteed. The response times are often inaccurate as they are not true grey to grey and also do not take input lag in to account.
If you are looking to overclock your monitor then I would go with the IPS panels as they do not need recalibration when running at a higher refresh rate.

Don't put too much credence in pixel perfect, if you read through the company warranties, they may change panels if you have dead pixels, however stuck pixels are allowed and to you and me a stuck pixel is as noticeable as a dead pixel! Overlord has a good explanation of panel quality.

Right now I would wait a little longer as Asus are going to bring out their 27in ROG Swift, which is a TN panel, but 2560x1440 at 120hz refresh and comes with Nvidia Gsync. It is rumored to be out in the next couple of weeks at $799. This price does not interest me, however it will only be a few weeks before a non-gsync version is released at a lower cost and other panels become available with 120hz refresh rate.
An alternative would be to look at the Overlord range of overclocked monitors 27 inch Monitors | Overlord Computer.

I have a 3 year old Dell U2711 and love 2560x1440, I would not go back to a smaller screen now.
I have been toying with the idea of a new 4K monitor. Even though I have a pair of R9-290's in CF that would be fine for 4K, I believe that I will be happier with a new 2560x1440 panel that I can run at a higher refresh rate.

So to answer your questions.
1: 4 or 6ms makes no difference to gameplay, however input lag can make a huge difference. This is one of the reasons why the Korean imports have a single DVI port and no OSD, to reduce lag. Some of these panels can also be overclocked, however this does affect picture clarity and gamma shift and without an OSD it is not always easy to recalibrate.
2: I do not believe that the Asus is worth it right now, read above. I believe that we will have a bunch of new panels soon with faster response rate at a similar price. If you want to buy now, then I would go with the Overlord.

Good luck.

Thanks for the link.

1) Shocked to read that overclocking 60hz 2k IPS displays is restricted to a DL-DVI connection! So Display Port 1.2, the only 4K 60hz compatible cable available today can't transfer 2K beyond 60hz?

2) I thought DL-DVI is limited to 2560x1600@60hz. What am I missing here?

Digital Visual Interface - Wikipedia, the free encyclopedia

Example display modes (dual link):
WQXGA (2,560 1,600) @ 60 Hz with GTF blanking (2 174 MHz) (30-inch or 762-millimetre Apple, Dell, Gateway, HP, NEC, Quinux, and Samsung LCDs)
WQXGA (2,560 1,600) @ 60 Hz with CVT-RB blanking (2 135 MHz) (30-inch or 762-millimetre Apple, Dell, Gateway, HP, NEC, Quinux, and Samsung LCDs)
WQXGA (2,560 1,600) @ 60 Hz with CVT-RB blanking (269 MHz) (This is for high end monitors when operating at greater than 24 bits per pixel.)
WQUXGA (3,840 2,400) @ 33 Hz with GTF blanking (2 159 MHz)

Replying to the rest of your post, with the priority of outputting 60 fps as a minimum in games, hardware today isn't ready for 4K but will be in 2 years time. The performance hit from 2K to 4K isn't worth it, but if I was in the market for a $600 TN monitor it would be the Samsung 4K and not the inferior ROG Swift, V-sync or not.
