i clicked specs, in the specifications table it's 3D: yes no 3D monitors support, and the link i provided shows the GPUs that are capable of running 3 monitors.
the GTX 295, 590 can run it without SLI becasue they are dual GPUs, the rest GPUs beging from GTX 460 (you need 2 × GTX 460).
begining from GTX 260 you need 3-way SLI (3 × GTX 260)
a single GTX 460 or 560Ti supports only 2 monitors, you need to SLI the GTX 560Ti to hook up 3rd monitor
ahh ok thanks~ i think im starting to understand, so even in NON 3D mode i still need another card to hook up the 3rd monitor?
If I want 3 monitor setup do you think I should return my card (bought card for 250) and get a multi-GPU or get another one of the same card which way is minimize the cost/maximum the gain? thanks~
