Re: How to install a second videocard (nvidia)?
Firstly, you can only instal a second card if you have a second pci-e spot....
Secondly... Nvidia cards don't crossfire! ATI/AMD do, its SLI in nvidia talk. Plus you need a sli capible board.
To use a second card for more monitors, get any card, I'd go a gts450 as its a fermi architecture like the 470.
I'm not up on PS, but i believe youre talking about the cuda support/processing PS now does, if so, yes, you can use the 2nd card as a monitor and a cuda/physic card.
What motherboard do you have as well what power supply?
2 cards need more power, and I'm thinking most likely you have agtleast 8x pci-e slot, not a 4x slot which hasn't been around in along time.
