I don't think for what most of us do day to day, we need one of the high performance cards which seem aimed squarely at gamers.
My old PC had a dual head Radeon 9700(128mb), which (Ithink) cost me @£120, 10 years ago.
It ran my 2 screens very ably.
It seems that some mid range cards now come with a 3 output and (I think), as long as 1 is DisplayPort' will run 3 monitors.
I have a 1GB Radeon 7570 with 2 outputs - again it seems more than upto the job of running graphically, typical software - CMC,IG,HL etc.
Both options in post 10115 seem to be about the same cost wise, either using a USB to VGA/DVI/HDMI lead and software or a run of the mill card such as
this.
Hils, I know that you have been a Matrox Quad fan for years - which one do you use? as there seem to be some on
ebay for a similar price to the Invidia above.
