I know that in 32bit OS progs are limited to 2gb max or so each, but why 
can't pov use a swap file like photoshop?

Yeah...

Damn....I'm going to have to break down and install XP Pro 64 I think...

I'd like to upgrade to quadcore first though, since its only like $200 now 
for the proc..

You don't happen to know what that "some setting" is that would let me use 
3gb for progs until then do you? That would really be useful...

I freakin swear, my next computer is going to have at least 1333mhz mobo 
bus, 16Gb+ DDR3 Ram, RAID5 10krpm SATA (SAS to much $$), 2x768mb nvidia 
geforce sli, eSATA ports, USB3 ports, xp pro 64...hells...I might even go 
for one of those nvidia Tesla systems...(wish I could snatch up one of the 
Cray CX1s...$30k tho..)

And if windows 7 actually does make you pay monthly for features else they 
get turned off, then screw it...I'm just going to drop windows altogether 
and run Mono and Ubuntu.
