unless you're playing bf3 or something of that nature. you dont really need more than 1 graphics card to run two 30" screens. a 6700/560 can easily run both screens of that size and resolution for osu and any low end games.(say cod, l4d2 and the like)
i can tell you now corin, i have 8hdd's 2 optical drives 12gb ddr3 and 3 gpu's, AND an overclocked cpu(3.6-3.8ghz, and occasionally 4ghz), and i use no more than 700w furmark/bitcoin/gaming. idle is 260w.
i dont get why people think they need a massive power supplies when the hardware doesn't need it. maybe when i throw waterblocks on my two 5870's and overclock them i'll need more than 850w, but stock clocks, i dont.
