I hear you on that one. Thinking of selling my main rig, and just using my E-350 rig to Nef.
Tried selling my Q9300 @ 3.0 rigs with HD4850 512MB cards on CL some time ago, no bites. So I'm using one of them for MW@Home. Not sure what to do with all of these PCs, if I can't afford to run them.
Yeah... I hope you can find a way to keep the fire alive
Consider buying a "S" IVB quad with what you get from selling your stuff and a nice 80+ PSU and forgo the GPU crunching? You might be able to really contribute on a 100W or less from the wall, and not much out of pocket when you factor in moving your current setup... Keep one of the GTX 460 for even infrequent gaming, maybe, as it'll like do nicely for years.... Just brainstorming for you
My "re-thinking" involves spinning up my 2600k rig for the PrimeGrid race this coming week - but possibly leaving the 1090t off... in PrimeGrid, that 2600k is worth almost two 1090's at at ~20% less power than one 1090, and stepping up the CPU in my main ESXi box from an i3 to an IVB "S" quad in the near future. It's an H61 board so OC'ing is out anyway.
Basically, I am going with CPU only for the rigs at my house - and moving towards CPU's that offer some real bang for the power consumed. Other strategically placed ones will have to carry the GPU burden. If you thinking of spinning off one of the 460's, let me know...
