Phraze there is no such thing as 460 ti. its either 460 or 560 ti.
And i've recently seen a review of the above monitor. It got excellent ratings, and review said no noticible lag or ghosting. But if you want, go for 120mhz. GTX 580 is a great card and a 120 mhz monitor will make the most of it.
yes sorry got mixed up, my card is a gtx550ti (i had to check the box)
I was more replying to trunk, he was the one with the 580 and will most likely have the fps to see some difference in anything other than the windows desk top
from what i can tell the best monitor for what i want and my current set up would be the Dell U2312HM (1080p). sadly the U2412HM (1200p) might be to much for my current card. as atm i'm only runing 1440x900 with 40ish frames
if i was the op i think i would go for something like the u2412HM over the 23
sounds like a battle between tn panels (120hz) and ips panels (60hz) here...
sure you might get faster refresh rates on your tn panel but unless you are pushing 100+fps it doesnt matter. also consider that tn panels have the worst viewing angles of any monitor and only so-so color accuracy. ips panels have a very wide viewing angle and (not e-ips) have better color accuracy.
as for future proofing, having a large screen reduces the amount of time between upgrades. for longer time between builds stay at 1080p.
i'm running a gtx470 and i'm pushing over 60 on all games i have. this includes crysis, supcom2, starcraft2 and the like. i use a 1080p screen.
for 2560x1600 you need to be packing a more serious graphics card (or multiples) which i do not want to budget for.
