hey folks, I've been away from here for quite a while so I lost the string of events... Today in an impulse I ordered a 2.26 octo with 8 gigs of memory and the Ati 4870. Will I need more RAM than with my actual 2006 3ghz x4 to run photoshop? Will I notice any significant speed increase...? Sorry if this is very old news for you guys; I did a search and found nothing comparing these 2 machines. Any other tip to optimize the machine are welcome. Bests!
