The GTX670's have managed to get me up to position 36 based upon RAC (Recent Average Credit) on GPUgrid which is what they spend their time processing. Considering I was down around position 150 or so about a month ago this is pretty good. More importantly they are contributing to some useful science.
We're still testing 7.0.31 which has a few minor changes since 7.0.28. I have reported one issue to do with project initialisation not honouring
I have been making some inquires with a number of manufacturers regarding coprocessors. I had initial email discussions with Adapteva who have a multi-core CPU, ClearSpeed who make a maths coprocessor and DRC regarding their FPGA offerings. Unfortunately all seem to have priced themselves around $10,000 which makes them too expensive for volunteers to use.
At the moment we're still waiting on Nvidia to release a GTX600 series card to replace the 560Ti. I have three GTX560Ti cards so I am keeping an eye on announcements. The main reason is electricity prices went up by another 18% this month, with the carbon tax getting the blame, and my electricty bill is getting rather large now.
I still need to find a case for the Adventure. Once I have one I will also need a machine to run it and might look for a relatively cheap AMD based motherboard. It doesn't need much CPU power as all it needs to do is drive a PCIe x16 slot to feed the Adventure.
