Well that is application/OS specific. > > Would I have to use the 64bit OS, or can I use the 32bit OS with the > mods (that I can't remember the name of) that Gus mentioned in 64 would be preferred and considerably easier. to do this with 32 bit you would need to compile a kernel with PAE enabled. Not really that difficult but a project in an of itself. Running 64 would be so much easier. As well as getting access to the additional RAM you also get full use of the Processor, something that 32 bit distros won't do. Running 32 bit distro on a 64 bit processor to me is like having a V8 and only running it on 4 cylinders. That being said, the benefits of having 4 or 8 GB of RAM will not necessarily be that dramatic to all users. If you don't have an application that makes use of that additional RAM there is not much benefit to you. However in general your multitasking between apps should be improved considerably. I run a Lenovo T61. 2.5GHz Core 2 duo and 4 GB RAM Intel graphics. Everything works out of the box with Linux. Suspend, etc.. I've pretty much ran a 64 bit distro since I got it. No complaints. I dock it with dual 1600x1200 monitors without issue. I did try a 32 bit, it was a horrible experience.
