I have a coolermaster hyper 212 plus cooling my processor in a centurion 590 chassis, is it good enough. I had seen a 2x GTX 460 review on tom's itself and they were using i7 980X at 4 Ghz, that is the why this question arose in my mind. Also, will it be a little more advantageous to go for 2x GTX 460 over 2x GTX 470, as to what I know GF104 is better than GF100 in price, temp, performance. Also will this set be good enough for 3 monitor at 1080p OR 23-24' 3D screen?
Then get your CPU at 3.4 if you want. At list that is the sweet spot for my core 2 duo(same socket). The gtx470 in sli will give you more performance then 2x gtx460 but the heat and power consumption will be higher(and the price also).
As for 3 monitors in games i know that AMD cards have that option. Nvidia has surround but i think only with 2. I won't say more because i do not know exactly.
I heard that MSI cyclone has fan fins that breaks off really easily when slightly bumped when you are doing some stuff inside your case...
I don't think you an break them that easy. NEVER WORK WITH A HAMMER INSIDE THE CASE . The fins might be a little more sensitive to bending but other than that the cards should be ok.
"..but what about a single 23' nvidia 1080p 3D monitor?" -Well that won't be a problem, but for more fps i would go with 2xgtx470. You will have an advantage when using a 3d monitor in demanding games. If i had the money, i would buy the best that i can. It depends on how much you want to invest in your video cards.
