I also have another question, and that is what be the cheapest GPU for me to get started mining some Ether? As I'm new GPU mining (and also my budget) I would like to get started with a cheap but decent GPU to mine some Ether. Any suggestions would be greatly appreciated.
You can probably start mining with any GPU or CPU that you already have. However some of the older GPUs may have problems because ethereum mining is memory hard and many older GPUs won't have enough memory.
But if you're going to be buying a GPU, stick to AMD cards as they are significantly better than nVidia cards for mining. If you're looking for something cheap get an older AMD 7870 or 6970 GPU. You can probably find them used for ~$100 each. If you want to spend a little more get yourself an AMD 7950/7970 or an AMD R9 280x for better hash rates.
Thanks for your recommendations regarding the cheapest GPUs I could buy. As I'm starting in this, I would buy a fair and used GPU, probably on ebay to start mining some Ether. This is so exciting. Even still, I have some difficulties setting up my Ether wallet (like knowing the right commands for sending and/or receiving Ether) but I will get the hang of it as soon as I finish this semester at college and then I would have more free time.
