Where in the UK can I buy a DVI to VGA converter to use another VGA monitor using the DVI socket on my GF4? I know these converters are around somewhere but i'm not sure where to buy though. On the subject of using 2 displays (or TwinView), who can tell me some examples of where you would find two displays useful? e.g. 1 display used for word processing and the other for some fancy full screen animation plugin with Winamp playing music.
