My Matrox G400max gave up the ghost last week. By a stroke of luck I had just been reading a shed load of reviews about graphics cards.
Based on what I'd gleaned I've purchased an ATI Radeon 7500 (just released in the UK). It has 64Mb of DDR memory, TV-out and supports two monitors, including digital out for appropriate LCD displays.
The card knocks the Matrox in to the Vauxhall Conference league. Unless you're in to heavy 3D gaming, you won't go wrong with this card - the reviews were spot on !!
If you are a Quake fan then consider the ATI RAdeon 8500 - it's got a slightly faster RAMDAC and is targeted at the high-end gaming market.
Hope this helps.
