Not really. I'd just use what you have. I don't understand why people will claim it is "not for gaming." It's a display. It will show the game, lol.
I do not understand "gaming" gear, apart from mice with multiple buttons such as the Razer Naga. I was a long time PC gamer in the past, since childhood, and most of that is pure marketing. I was ranked in the top 50 worldwide in the BF2 days with a green tinted CRT monitor, dusty membrane keyboard and a Microsoft Mouse ffs. Don't buy a "gaming monitor" if you're going to get something new.
I pretty much agree with all this - I can be just as competitive with a BlueTooth Magic Mouse or even a $10 RF IR mouse vs. a $100 gaming mouse with it's "L337 1ms response time" - it's all marketing. I generally own people with such budget mice whom I can only assume have the high end gaming stuff.
As for refresh rate, I've heard it is noticeably different, but really, I doubt anyone can ultimately win a match due to that alone.
Display image quality, design, elegance, and build quality *FAR* outclass anything "gaming" about a monitor - I currently game at a competitive skill level on my Mac Pro with 20" Cinema Display using a Magic Mouse after I sold my GTX 760 i5 gaming PC I build about half a year ago, and I don't miss it at all, besides Windows only games.
I have another 20" aluminum ACD and if and when I get another Windows box to complement my Mac Pro, you can bet I'll be using that monitor, unless Razer or someone comes out with an equally well built and elegant monitor, then I'd get that if only to have a newer, higher rez panel. That's it.
Bottomline - if you can't notice any distracting ghosting with a panel, it's fine for gaming.
