Sorry if this is a noob question. I have just come to the choice of picking 64 or 32 bit CentOs. My processor is 64bit and I have heard 64bit can be faster and has more expansion capaability. The only issue I am worried about is software capability. I need to have FFMPEG, clam av, and x264 libraries installed. Would a 64bit installation affect the ability to run certain programs in general?
Unless you have a very small amount of memory or intend to run your memory at >95% all the time then you'll be fine with 64-bit and it'll scale better too :)
