So I just got a new 64 bit system the i7 (quad core) processor with 6 GB of Ram and while I was at it upgraded to the CS4 Creative Suite - Production Premium...a lot to take on all at once but still have my old sytem running as back up.
Anyway, I'm slowly delving into everything ( i wasn't even on Vista yet before this), lots of housekeeping to do before I go full speed ahead. Still have only gotten to really get using the Premiere (which I've already found 2 bugs in). However, hope to be using all programs a lot more soon (Illustrator and Soundbooth I'm not all that familiar with so don't count those) and can answer questions with regard to CS4 for anyone who might be thinking about an upgrade.
So far, I find the system to be fast (although not quite as fast as I imagined but a vast improvement). Some nice features in CS4 but nothing I couldn't have lived without. I upgraded for 3 real reasons 1. to make sure I was compatitble now that I went to the i7 processor (CS3 seems to be working after all but does have some issues). 2. dynamic link which you can only get with a suite 3. the very cool blend modes now in Premiere CS4.
Anyway, more to report as I get to using it more. Again, if anyone has any question I'm happy to report what I know of the new features.
