Eyefinity cards question

I currently have 3 monitors, 2 on a HD3870 and 1 on the IGP of the 785G mobo in surroundview mode, and am thinking of upgrading my vid card to a HD 5xxx series. I know you need an active adapter to do Eyefinity but what if you are simply extending the desktop as I currently have? I keep one monitor in portrait mode for the internet but the other two are in landscape mode. Do I still need an active adapter for this?
 
Actually, you 'can' use a passive adaptor for general use, but you limit your refresh rate, and it's not guaranteed.
 
or he could just replace the 3870 with the 5xxx and keep the 3rd monitor on the IGP. No adapter needed.

The difficulty with my current solution is that when I maximize a video on the monitor connected to the IGP, Win 7 Aero turns off after giving me a message that Windows is low on memory. I view a lot of MKV files so the error crops up and I figured a 5xxx card would eliminate this.
 
How much system memory do you have? This will be shared with the IGP so if you're low on system memory it would give you that error.

I had 2 HD4850 before going to 3 24" monitors and even when stretching a mkv video file across 3 monitors I never had any memory problems. The 4850 had 512MB each with 4gb of system memory.
