|If you can get by with a desktop version of a computer you will get more of everything for the same cash. |
What exactly do you need the computer to do? What type of rendering are you planning on doing? What games do you play?
I assume you are located in India. You may have limited options there. One thing I have noticed from posts here is that the power supplies generally available in India are not good ones. Any desktop computer you decide on should have a good power supply. For the most part, pre-configured desktops from companies like Dell only install a power supply strong enough to power the hardware they ship. So if you plan on buying something like a Dell, you should be sure you order it with the hardware you will need.
