No, it is enough processor will be available from mid-range, which will be optimal in terms of price / performance. At the moment, if you have limited budget, then you fit processors IntelPentium Dual-Core E2180 (2.0GHz, 1MB L2), AMD Athlon 64X2 5000 + (2.6GHz, 1MB L2) or AMD Athlon 64X2 5200 + (2.7Ggts, 2MB L2). For the price, it's more processors budgetary level. In terms of performance, these processors are easily cope with rendering video, encoding, working in video editors and other resource-intensive tasks. Perhaps check out MasterClass Founder for more information. If you have sufficient funds, then the optimal choice will be the following models: From Intel is IntelPentium Core 2 Duo E7300 (2.66GHz, 3MB L2) from AMD is the AMD Phenom X3 8450 (2.1GHz, 512KB x3 L2) which is great parallelizes intensive tasks, downloading with all three cores, or AMD Athlon 64X2 6000 + (3.06GHz, 2x 1MB L2). Motherboard. Choosing a motherboard is primarily confined to the properties of future CPU: need the same socket, and a compatible, preferably the most advanced, chipset (chipset). But in Basically, all sorts of extra gadgets and bells and whistles you do not to anything, so choose a quality motherboard from the middle price range.
The only thing that is desirable is the availability of on-board IEEE port for connecting digital cameras, but if not, no problem, this port can be bought separately, the benefit is it inexpensive. For processors from Intel, for systems budget level chosen motherboard chipset Intel P35 Express. To choose an optimal system motherboards on Intel P45 chipset with a bus bandwidth FSB> 2GHz.
