Thank you for the advice dario, i'm not sure about how the software utilizes the cores and I could probably get by just fine with a lower end graphics card. The only thing I need the graphics card for is to preview the movies during the editing process, the program limits the amount of ram is used by the player to keep essential ram available for more important functions, and it's all customizeable in the preferences. I just need to keep in mind that when playback skips during preview it won't after producing and burning to disc. The budget I mentioned is definitely subject to change because I want to leave room to upgrade as technology advances every ten minutes.
after reading forums at avsforum.com i have learned that sony vegas 9 does utilize cores of one's processor, thanks for the tip on that dario.
