Answer 1

Seems like you have very much overkill in certain areas and not enough in others. If you will be running Dreamweaver, you don't need a lot of RAM! If, on the other hand you will be using Photoshop, you need a lot of RAM. I've been using Photoshop since 1992 and the more RAM the better, up to about 6 GIGs, then it really doesn' make much of a difference. As for the Graphics cards, not sure why you need 2?? I use Photoshop professionally and have never needed 2. As for the RAM, the graphics cards have their own RAM built in and it should not rob from you system. I use a Quad processor HP running Vista 64 bit. Photoshop flys, as do my other programs. However, I will tell you, if you change to 64 bit, be prepared to upgrade most all of your software, and on top of that, a lot of software is not capitable with 64 bit at this time. I played Hell getting my system set up running 64 bit. If you are not going to be using Photoshop, which is RAM hungry, you do not need more that 4 gigs of RAM.
