Current
2 x 9800 GTXs @ 766/1915/1148
-> I need to unlink the core and shaders, drop the core clock and boost the shader clock. This would get me a few extra hundred PPD. Now I'm running the GPU2 console clients on these, not the systray clients. With my OC on these I've managed to get at least 4200 PPD (on 511 pointers which usually are done in 2 hours 50 minutes) and upwards of 6600PPD (though I can't remember the high end off hand).
Core 2 Duo E8500 @ 3.8 GHz
-> I got here by only bumping the FSB to 400. I could probably squeeze alot more out of this and still have it be a fine 24h OC, but I'm brand new to OC'ing so I haven't broken out of my shell yet. On this I'm running VMWare folding, which allows me to take advantage of the A2 core for Linux. In the coming days I'll be grabbing some USB flash drives (3 total). Reason being is that the VMWare virtual disk 'runs out of room' for lack of a more technical explanation. This lowers my PPD by around 500 - 1000 in total. However when saving to a USB drive instead of a virtual disk, this error does not occur. 1 Flash drive will be used for the E8500, 2 will be used for my upcoming project. At the top end, she pulls 3300PPD however due to the 'attempt to access beyond end of device' error it soon drops to 2300 - 2700 PPD. Before VMWare I'd average 1400-1700.
Planned
2 x GTX 260 216 (65nm or 55nm)
-> I'm not sure of the clocks but they will be OC'd as well to a nice stable OC. Again I'm not going balls to the wall on this, only getting more out of them. These will run the console client.
Core 2 Quad Q9450
-> I tested this briefly before booting up my main rig again (only 1 power supply at the moment). I was able to OC it with a 400FSB easily, and again I'm sure I can reach higher clocks. It will be running 2 VMWare clients saving to two USB flash drives (you need to keep 1 USB drive per VMWare client).
I average 12-14k with my current setup, and I hope to bring out an additional 15-18k with my planned setup. Where I'll stand at the end of it, I'm not sure as I'm not 100% on the PPDs I'd be pulling from my planned, or how much of a gain I'd see in fixing my VMWare client.
