Upgrading my graphics card to one with an s-video output
I'm looking to upgrade the graphics card on my Dell Precision 360, to one that has an s-video output for my TV. The trouble is my machine is quite old, maybe even 10yrs - I can't remember when I bought it!
My concern is that I don't want to buy a card that is incompatible with my motherboard, but I have no idea what the interface of my current card is, nor how things have changed since I bought it (I assume there are various standards). I also don't want to buy a new card that performs worse than my old one.
I know that the current card is an nVIDIA Quadro FX500. Beyond that I'm clueless.
Can anyone tell me how to find out what specs I should look for in a modern card to ensure compatibility, or point me to an area of the Dell website that can tell me the full specs of my current card?
