definitely +1, would donate
my minimum (but rather better):
matte 24" 1920x1080@144Hz+ (ofc 1920x1200 is ok)
For me (gaming monitor) and you (money), I would not go much crazy about PPI (pixel-per-inch), because UI can get easly broken and people can get wtf-is-this if you start pushing "big res" to "small monitor" or otherwise, so I would stay in current PPI standarts (1920x1080-24"), (2560x1440-27"), ... And I don't know how these SEDs/FEDs works, but on CRT (EIZO F931) if you have 1600x1200@104 on desktop and 1280x1024@120 in-game and alt-tabs, refresh-rate downgrades to lower one, sometimes helps to change it back in menu, but it is a pain (got even autohotkey macro for that

)
Imho for succesful business, depends on release date, but
monitor 6 looks like gamers choice for now and I think it will for some time, because at least in gaming 1920x1080 will be there as a standart (HW of next-gen consoles must catch up with in-game graphics demand), plus you will have superior refresh rate, no latency, no input lag, no ghosting, epic colors advantage, so no need for 2560x1440, maybe even no G-Sync and people will buy it.
If you want cover DTP, go second monitor, because you don't need high refresh rate, on other side size of a monitor and resolution is NUMBER ONE. If you try to pull both monitors together and make compromise, people will go wtf-is-this again feeling and your monitor will lose the edge.
Don't want masturbate my ego here, rather trying to point out my experience, of course it does not guarantee my observation skill, but... anyway tryharding in increasing manner BF2/BC2/BF3/BF4 last 8 years on ESL, went thru National Championships, zillions cups, 2x ESL One Season in BF4, and ofc many other games for fun like Quake...
My monitor experience: CRT 17" 1280x1024@85Hz > LCD 19" 1280x1024@60Hz (for a week) > CRT 19" 1280x1024@100Hz > Acer gd245hq 1920x1080@120Hz > CRT 21" (EIZO F931) 1600x1200@104Hz > BenQ XL2420T 1920x1080@120Hz > BenQ XL2411T rev1 1920x1080@144Hz > BenQ XL2411T rev2 1920x1080@144Hz > BenQ XL2411Z 1920x1080@144Hz
My mouse experience (not in this order): MS IMO 1.1a, MS IE 3.0, Razer DA 3.5, Ikari Laser, Logitech MX 518, G5, Razer Lachesis, SS Kana (winner), Zowie AM, tested for short time others...
Plus another tweaks to make my gaming smoother...
