GUIMiner: New miner option confussion

[mettam]

When I create a new_miner with GUIMiner I get these options:

  New OpenCL miner
  New CG miner
  New CUDA miner
  New Ufasoft CPU miner
  Other new miner

Could someone please explain to me what they mean.

The gist of the different miners is that they have different capabilities for different hardware and/or different extensions for mining pools. You may want to check out this wiki page to see how they differ: https://en.bitcoin.it/wiki/Mining_software

Thanks for the link, but it's still not clear to me how to decipher this list. My hardware is a Nvidia_Quadro_2000 and I am running windows8 on a Intel Core i7-3770k. 
Which miner would you suggest I pick ?

I'd make the recommendation that you try them all and pick the one that works best with your hardware. Cross reference these wiki pages: https://en.bitcoin.it/wiki/Mining_hardware_comparison and https://de.bitcoin.it/wiki/Mining_hardware#Nvidia
You can see what hash rates people are getting for similar hardware. Some entries also have some of the command line arguments for the different miners you can try too.

Don't forget to be aware of your power consumption. Unfortunately Nvidia hardware isn't the most efficient for mining bitcoin.

GUIminer gives me the option to use my GPU or my CPU's . It seems everyone talks about using the GPU and not the CPU. why is this ? Should I forget about using my 8 cpu's and instead just use my Nvidia_Quadro_2000

Mining with a CPU hasn't made much sense for a while now. Check out this wiki article in answer to your question: https://en.bitcoin.it/wiki/Why_a_GPU_mines_faster_than_a_CPU

https://www.weusecoins.com/en/mining-guide also offers some good information to read.

Unfortunately, with the hardware you have it may not make sense to mine if you account for your electricity costs. It comes down to what your motivations are for mining.

According to this link you sent me https://en.bitcoin.it/wiki/Mining_hardware_comparison#Popular_Mining_Cards the BitForce Mini Rig 'SC' can mine at 1,500,000 Mhash/s. It makes my Quadro_2000 at 26Mhash/s look ridiculous. Also with this Bitcoin Mining Calculator, if I put in 1500000 Mhash's that the BitForce Mini Rig 'SC' mines at. This computer can generate $250,000 per month !? Is this true or have I got my numbers wrong ?

[rich90usa]

It's more or less true, but that hardware doesn't exist in the general population having it. I'd only count the ones with the green 'shipping' box from that chart.
