and i want to buy a good one for mining...can somebody guide me please?
thankyou inadvance

I am speaking from experience right now. I have 5 desktops running in my office at work and I am not making much from them at all. They are all good systems and they make me a few altcoins per month, but they are not worth the electric they are using. Now if you have free electric like I do, then it is worth the time for you to do it. If you look hard enough, you will make more money in signature campaigns than you will mining with a desktop computer.
