I currently have a AMD Sempron M120 2.10 GHz processor and Sony Vegas is very frustrating when I'm trying to use high quality clips. I can't even play a clip that doesn't have any effects at all added to it without it searching for the frame the whole time I am playing it . I understand about the build dynamic ram preview option and the selectivly prerender video option but it is very annoying having to wait for 5 min for a 5 second clip to play that I barley modified. So my question is what is the fastest processor that I can buy that can fix this problem in sony vegas and will be able to handle after effects in the future? All under 500$ if that is possible.
