Hi! So, I have just this question: What would be good on a 64bits system over a 32bits one? Ok, I got a Athlon 64 (finally), but now I'm just asking myself: Will the time an effort of installing a 64bits system serve of anything else than telling my friends that I have one?, please note that I use this computer as my desktop computer, so I will run there: openoffice.org, firefox with plugins (specially flash), doom3 (wich somebody told me that will run in pure64 without problems), and 32bits versions of: mplayer and maybe transcode (if it happends to be slower in the 64bits native system).
My guess is that the 64bits binaries (besides being larger), should be faster (at least a little faster), is this true? I have read about other programs (mplayer, transcode) that run slower, due to problems with the optimizations (mmx, sse, 3dnow) not working. Thanks in advance for your help, Ildefonso.
