PIE - Perfection In Execution

[trn]

3 x 460's might work out nice also depending on exactly the PPD they average. 3 x 40,000 - 50,000 = 120,000 - 150,000ppd and wattage should be ~450w. I think 240's avg 18,000 or so and 80w = 108,000ppd and 480w; the price is great though with some of them being $40 after rebate = $240.

I'm unfamiliar with the i5/i3 1156 boards and if they have 3 pci-e that would fit 3 dual slot cards. Maybe a low cost 32nm i3/i5 may make a good low power GPU crunching host, 70 - 80w under load might be nice. Not much good for CPU crunching but you can dedicate 100% of the cpu for GPUgrid and have lower power usage from the cpu and lower cpu/mobo cost?

nm, a quick newegg search shows 1156 boards are no good for fitting 3 gpu's
