Ok, so I'm thinking of starting the ball rolling soon with a looooong overdue upgrade to my PC. In order to get more usable system memory I'm thinking of changing to a 64 bit version of Windows. Unfortunately my budget would in no way allow me to spring for a 64 bit copy of PS and so I was wondering if there would be any potential problems for me running 32 bit PS on 64 bit Windows? Any compatability problems or bottlenecks or whatever?

I remember reading that 64 bit PS had compatability problems with some filters. Is that right? It is just the PS version that causes that and not Windows itself?

Cheers in advance for your help.
