Building a new system this summer, and have built systems in the past, but need some advice about my graphics setup I'm hoping to do.
Build as of right now (not including stuff like hard drives and such):
ASUS P6X58D Premium mobo
Intel Core i7-920 Bloomfield cpu
G.Skill 6GB RAM
PNY Quadro FX 1800 Workstation Video Card
Windows 7 Ultimate 64-bit
Currently I'm getting into the rather mind-boggling, but fun, field of 3D editing and creation, which is why I chose the NVidia workstation card as my (first) graphics card.... but being a fan of video games as well I'm looking into getting an additional graphics card for the system, hooked up to a separate monitor.
So, my question is, could I put the Nvidia workstation card attached to one monitor, and then put an ATI 5XXX (not sure which one I want yet) gaming card into another PCI-e slot attached to a separate monitor into the same system?
What you are proposing is entirely feasible, although if you wish to use an Nvidia card and an ATi card together you won't be able to use Vista as only XP and W7 allow you to run two different VGA drivers.
