[Or Zamir] “I will buy i7 3770 and 16GB RAM, now my question is:
Do I have to buy external GPU or the Intel HD graphics 4000 will run Vegas fine?”

Vegas does not require a fast GPU. It can use one, via OpenCL, to accelerate some rendering activity. However, it seems to be the case that, the faster your CPU, the less GPU rendering is going to help you. This kind of makes sense — there’s an unavoidable overhead when Vegas has to code up a render for the GPU, send it, wait on GPU completion, etc. When your CPU is relatively weak and your GPU relatively strong, this is worthwhile. When your CPU is very fast, it may well be faster to use the CPU for everything. I expect that, in time, Vegas will become more efficient in this overhead part, if Sony really puts in the development time (seems to be the case that Adobe has, so that kind of sets a bar of possible achievement that Vegas hasn’t met, yet).

In your case, the CPU is one of the faster available.. I put an i7-3770 in the PC I built for my Son’s birthday, and got one in my work computer a few weeks later (Karma?). Not sure if the GPU is much of an issue in such a system, but it’s definitely not required.
