Ok, I'm looking for a machine in a category I'm not all that familiar with, so I'm looking for some suggestions. I'm doing some research where I need some fairly serious quantities of memory. Although my work is computationally intensive, at this point, memory size is even more critical. I'm looking to buy a system with 4GB of RAM, but this is a minimum...I want to be able to upgrade this at a later point when 4GB runs out, and when I have some more funding. I'm hoping for dual processor with an extra socket for a second processor later, but I'm open to other options (even if I can never go above 2 processors total...either 1 dual core, or 2 single core). Platform isn't really that important...x86, PPC, Sparc, etc....doesn't matter. At this point I don't even care about OS, since all of the software is written in Java. My budget is limited, but (hopefully) not unreasonable.... Suggest away! Thanks.
