Film and television production software has multi-core optimization, that is, the more CPU cores, the faster. So I ruled out the I3 scheme. X4 640 poor computing power (personal opinion) can also be ruled out. The only remaining options are I5 and X4 955. In terms of computing performance, the performance of X4 955 is far less than that of I5, but the price of I5 is relatively high. Post-production of film and television requires high processing power of CPU. If the landlord's budget is not tight, I suggest adopting the I5 scheme. Another 8G of memory is essential. The power supply is not enough. To ensure the rated power supply of 450W W, the burner is essential. In the later stage of film and television, some works are often made into CDs for customers to see, so the location of the burner is very important.
