19" or 20" Widescreen for gaming?

[spinna]

ive been reading loads of posts for Widescreen LCD Monitors but i still cant decide what to go for .
ive been looking at these 3 monitors :

Acer AL1916W 19" Widescreen £187.94
Acer AL2016Ws 20" Widescreen £287.82
Belinea 102035W 20.1" Widescreen £328.94

ive got a 17" lcd monitor at the moment and ive decided to get a Widescreen one. i play a lot of games so which is a good monitor to play them on?
are the 20" monitors worth paying the extra £££?
thanks
