I have a single XFX 7870 ghz dd 2gb edition card at the moment and I use eyefinity at 3x1080 (6036x1080) and i need more power.

Do I add in a second card for $200 bucks or get a new 4gb card due to the need for more vram.
I play any and all games i can get ahold of. Crysis1,2,3, Farcry1,2,3, Just Cause1,2, Fallout 3& NV, Batman Arkam City, Battlefield 3,4,Skyrim, and Borderlands1,2., Blacklight retribution. Dirt 3, Darksiders1,2, Need for Speed world. World of Tanks/Warplanes, Star Trek online.

I do like physx alot but is it worth the switch to nvidia cause the price is higher. and the vram band with is shared on the 4gb 770. What is the best plan here? I need not exceed $400.
