Does anyone recommend a vid card to run the new 23" Cinema displays on an older Dual 1.8 G5? I bought my computer in the summer of 2004, and just recently bought a new HD cinema display... only to find out I need a new vid card to run it. I've seen some in the $500 range, but they are capable of running two 30" monitors. i don't need that much power... just enough to run the one 23". Any suggestions? Please help because my new "non-working" display looks pretty lame just sitting on my desk. =( sorry in advance if this question has been asked a billion times.
