So as I am a newbie in folding (only 49 days so far) I have been trying different hardware combinations, clients and OS to see what gives best performance for cost and efficiency. Its been a interesting journey so far and very addictive. i had a few people asking what kit i been using to achieve the rapid climb within the team so i though i give a small summary of the components Rig 1 - Watercooled Nvidia Asus Titan's 12GB are the kings of folding in my opinion. I got two of them overclocked (boosts to 1422Mhz) and temps do not rise above 40C degrees at full load pushing out 1M -1.2M ppd. Intel 5960x 8 core cpu watercooled, overclocked to 4.2Ghz (from 3.0Ghz) running web browser folding client Rig 2 Aircooled 2x Gigabyte 980ti (my favorite gpu for gaming) also folding, overclocked (boosts to 1550Mhz) and this is also pushing out 1M ppd. Intel 4790K overclocked to 4.6Ghz I also have several servers (dual cpu Quad Xeon x5570 with different gpu folding now and again; MSI 970 GTX - OC boosts 1533Mhz, 48C - 280k- 320k ppd EVGA 690 GTX (dual gpu in 1 pcb) - OC boosts to 1228Mhz, 68C, 180k-230k ppd (quite disapppoint with its performance) I also had a few AMD graphics cards, MSI R9 390 8G, R7 370 4G and R9 290x but again they did not perform as good as nvidia cards and they pulled a lot of power at the wall so I decided to not use them, sell them and get more 970gtx (another one arriving next week) After testing 3x HP Z600 servers, 1x HP Z800 and tinkering with a evga sr2 server, i decided to sell them all and build 1 mega folding PC based on a server platfform. The reason for this is simply because i want permanent folding rig with the capability of folding 2-3million million points on its own and also utilise it for video rendering/editing projects. Also my Rig 1 will be up for sale this month so I need to build another to replace and exceed its performance to get contributing to the cause. So if anyone is interesting in buying these servers, or my main rig, let me know. Pictures, videos of them can be found on social media and Youtube.

In regards to gpu's to go in them there will be 7 x 970GTX's using usb pci express risers to begin. Solution for electricity consumption will be a 18 panels Solar panels installation probably in September this year.
