Thanks for the reply, it is apreciated. Russell Coker said,
The limit on per-process address space (which isn't just a limit on memory use) is the main thing. Also there are performance issues with PAE.
The problem with claims of performance differences is that an awefull lot of things can effect this and I have only seen one report (of 32 v 64 bit) giving full details and test results of said tests. These showed some things were faster and some were not. There are plenty of sites claiming performance enhancements of 64 bit, almost none (only a single site) gives any real evidence, most sites __clearly__ cherry picking data. This sort of thing makes me __very__ sceptical as if something really is faster one will see benchmarks published all over the place.
Have you enabled multi-arch?
Yes, the last remaining problem is getting the closed src driver working everything I have tried so far leads to the same thing. The X server crashing after start up from a memory violation to do with a font library. This is also with Debian Stable AND sid, four different kernels, two of Debian's the others my own and of course two differnt vserions of xorg. I am going to try i386 to see what will happen, I may add I have never had the current graphics card an NVidia GTX 680 working on a closed src driver under linux, works __mostly__ great under the open src driver. The card works great under Windows XP. Lindsay
