LCD's are great on the eyes. They have laser sharp text and everything is crystal clear. The problem with LCD's is their streaking/ghosting effect. Let me tell you that it's a bit touch and go. I have a Samsung 173p, which has a response time of 25ms. I can play fast paced games like Unreal Tournament 2004 in it just fine. But when I play Counter-Strike the ghosting toasts my eyes like no other - I can't play it on this monitor because it starts to physically hurt and it effects my aim. I don't really know why there's this large difference but it's there - I can definately notice streaking on CS, but on UT2K it is well below tolerable levels.
Since I'm worried about CS:Source streaking as well as HL2 and D3 I'm RMAing my monitor and getting a 710T, which has a 12ms response time. I'll let you know how that one works out when it arrives on Tuesday/Wed.
CLIFF NOTES: CRT > LCD for games/movies, LCD > CRT for everything else.
