i have a BLAZING computer, 3ghz intel extreme quad core, 8MB super fast ram, and a really good board.  the video is the slowest part because i got them mainly for Poser not for games, i have 2x 8600 GT - 512mb cards.

so if i make a significant video upgrade can i expect a preview speed increase?  that would really improve my business as i sometimes do scenes with 3 or 4 characters for work and preview crawls... although now that i have fixed OpenGL preview its a lot faster than SreeD :D

im just wondering if i should bother upgrading or not.  i will need to get 2 of the same card, which i certainly don't mind doing- cost isn't the issue- it's just that i have no time for games anymore and it would need to be worth it for poser.

Also- i have SLI turned off because one card is hooked to my projector.  does SLI affect poser performance in any way?

thanks!!
