I have a 3.06 HT PH with 2gb DDR400 ram (1gbx2) in dual channel.
I want faster rendering and the ability to view my timeline in real
time no matter how big I make it. I already have a Canopus ADVC300 to
capture and also to view my edit on an NTSC monitor. My system is
pretty good as it is and I do not use fancy transitions and such,
mostly dissolves, color correction, wipes and titles. Would you
recommend that I go for another 2 GB of ram or would I see a greater
benefit from a Matrox RT.X100 or Canopus DVStorm2 Pro (which I have
heard has compatibility problems with Premiere Pro)?

I get about 4 jobs a month and would like to make my turn around time
a little faster.

Any suggestions is appreciated, thank you.
