Sorry, but Nvidia cards just don't have the amount of stream processors necessary to mine at a decent rate. Go with AMD.

1200 billion 32-bit operations per sec / 4300 operations = 280MH/s

Elsewhere on the forum seem to suggest something like 280MH/s.

Reckon it might be pretty good for sCrypt???

What about the Xeon Phi??? More Threads than my 5850.
Could get a decent hash rate off that?
Lol no

its not a bug. by default the cpu miner will use an available OpenCL device.

add the following flag for CPU only: -g no

you can also specify the number of threads you want with this: -t 8

on my notebook (i7 and a gt425m), i do: -t 7 -g no

OK that makes more sense. I had not added the flags.

Well using bitcoin-miner.exe It shows 325-350MH/s. If I switch to rpcminer-cpu.exe it reports about 5.5Mh/s. Must be a bug like m4dhatter said.

Has to be some sort of bug. When I was using my gtx 460 to mine, if I clocked it to high the driver would crash. When the screen came back on guiminer would report a hash rate of 200 Ghash. This would continue until i rebooted the computer. I'm not saying your issue is the same, only that falsely reported hash rates are possible if things aren't running correctly.

Can't be true. My 2600k at 3.8GHz, mining with all 8 threads, pulls a whopping 66 Mhash/s. Very variable though, shoots up to 100 and down to 35-40 at times, with 60s on average.

(edit) with "-g no" (see below) it gets a meek 16Mhash/s, which is the true number... This is Intel's latest and greatest CPU BTW.

Everyone has been stating that GPU is only way to hash and CPU hashrate is too low to really be worth it now. I am pulling up to 350Mh/s on my i7 975 extreme OC'd to 4GHz. Its water cooled and is stable. Are their other disadvantages I am not thinking about like power consumption? Is it more or less the same as a GPU power wise?
