+1 on the Samsung. I usually go with Samsung monitors and have always been very happy with their performance. The HD6870 I have does game nicely at 1920x1080 and I run pretty much maxed out. Up to you to go single or CF (my next adventure as well with my primary gaming rig).
Yeah but have you tried STALKER or METRO? Good luck maxing that out even at 1680x1050.
