Use two nVidia cards, but don't forget to upgrade your PSU and cooling at the same time.
Whether that is worth it on a Core2Duo system is another question.
i agree with harm.
i have 2 nvidia cards.
i upgraded my cooling on the cpu with a noctua
and am in the process of solving how to keep the temp
down on the 2nd gpu
2 identical nvidia gpus with at least 1gb of ram each
provides you with the ability to run 4 monitors
(though PPRO will only take advantage of 1 gpu for MPE)
i still think it is wayworth it, though...
Thanks for your reply. I was hoping that it would not be necessary to
buy 2 new cards but it seems the only way to go to achieve my 3 displays
and get GPU acceleration. I must also upgrade my system as well!!
