ok another update,

i loaded up the completed Mpg files into studio, and i dont hear any choppyness in the audio... only in media player when playing back.....

 ill obviously import the hi-res version to keep the quality as high as possible, as Im not sure yet if i will burn hi-d or DVD or both

i stil feel like there is something holding the computer back...some type of bottleneck thats slowing everyything else sown....  could it really be the video card ? 

 
If i were to buy a best possible video card for the purposes of video editing.. what would it be guys ??  i am willing to spend anything to get what i need at this point !

thanks
