Thanks for the input. When I get the money, I'm going to get at least 8 gigs of ram installed.
Yes, absolutely. And the 64-bit OS to go with it. I just jumped from 4-gig on a Vista-32 bit, to 8 gig on a Win-7 64-bit. Bit difference with Photoshop. I still "suffer" with a dual-core processor, but my Mobo is a little old and won't handle any but the oldest, slowest quads. Still, an E8500 at 3,8 GHZ isn't bad, and is certainly a little faster than the 6750 it replaced.
If I was a gamer, I'd be looking at things a little differently.
