Check out my rigs if you'd like. Personally, I don't like gaming on 3 screens, and I absolutely hate gaming in 3D lol. I've tried both a fair bit. I do however love the 120hz that 3d-ready screens have, and am quite happy with GTX 580s so far. I had 560 Ti SLI before, and definitely prefer a single 580.
If you wanted to get a cheaper card you could - the 560 Ti or 570 are great choices, but slightly less powerful.
Yea I'm defiantly going 3 screens. And I'm going to go 3d since I have some extra moony to pu for a 3d monitor so I'll have one of the acer monitors you showed me .. So I'm just going to keep the card you advised and just get the one year warranty unless they already have one .... Should I put a warranty on my mobocracy and CPU?
Honestly, get a card with a better warranty. The zotac is 2 years, but with this system you will have it for 5+ years most likely. This EVGA is only $50 more and comes with lifetime unlimited warranty: http://www.newegg.com/Product/Product.aspx?Item=N82E168... I know it's a bit more, but you won't be unhappy. EVGA makes amazing products.
