I hope V will be much better then IV, they should make something more like San Andreas with improved gameplay & graphic, since GTAIV is more like downhill for me IMO
for internet use, I'll go with Dell, since they have the same resolution, but Dell is 24", Samsung is 27" which I believe that the graphic will go sharper (for Dell) IMHO :)
the link you provide didn't work
EDIT : It's work, my bad :D
I hope someone will help you soon as I'm also on learning stage on how to overclock :) GL buddy :)
