So "Mostly my friends use Xeon" CPU's.
Really !!! Less than 0.01% of home computer users (including enthusiasts) use a business grade CPU (which is what a Xeon is).
Where do you live? What computer equipment is available to you? If you are in eastern Europe or somewhere else outside of the main sphere of retail influence then fair enough. There are much cheaper platforms available to you than Xeon.
Be more specific about what you need it for. Are you doing casual or full blown video and photo editing. Are you doing image manipulation and creation. It's not all about what CPU you have. The graphics capability are vital. How much gaming do you intend to do and what games are you playing?
Edit: Okay sussed you're from Lithuania. None the less we need to know specifically what you want to do with your PC. Including the equipment you are using to get your images.
