What is the advantage of dual video cards?

Answer 1

multiple graphics cards increases the performance of the computer significantly. up to 3 cards can be linked together using Nvidia's

"SLI" or 2 using ATI's

"crossfire". the increase in performance largely relies on the game or application being run as most games are not designed to be run or more than 1 card.

what planet you on it's 4 with ATI and with ATI you can mix and match as long as they say 4000 with 4000 and 5000 with 5000 exc

also ATI only need 1 video card for dual monitors Nvidia

you need 2 video cards for more then 1 monitor 3 max monitor 6 max ATI and can be done with 1 card

with ATI and the right motherboard that supports Lucid HydraLogix ATI crossfire technology your and max and match just about any ATI GPU
