Dual moniter GPU setup

i wanna do a dual monitor setup and i need some answers on which GPU to use, its either the GTX 970 or R9 290. i plan on gaming at 1080p and I don't really care about price (at this moment). I want something from sapphire do Asus. Also, do i need two cards for two monitors or can i do it all off of one. 

1: if money isnt a thing then go with the GTX970, its simply faster at 1080p.

2: No you dont need 2 cards. You can hook up to 3 or 4 displays on a single card. just look which connectors you wanne use.

You can easily push two monitors at 1080p with either... The question is more.... Why would you want to on two monitors? on any FPS your crosshairs will be split on the bezel... I'd recommend either three or playing in windowed mode and using alt-tab for game guides or whatnot... Three monitors give you an awesome peripheral experience... But you can't set it to just give you a left or right peripheral that I'm aware of... but to answer your question... the 970 is considerably more powerful and worth the extra $50-70 IMHO
