i want to know whether i can use a software on my desktop pentium 4 @1.6
the requirement for software is 2.4 ghz .
i also want to know what it(line below) means in pentium 4 dual core processor
Its also probably a reference to the jump from the netburst (P4 and Pentium D) to the Core architecture (Core 2 Duo) which is much more efficient per hz. For instance my single core Celeron 430 system at 1.8 GHz is much much faster than my old P4 @ 2.4 Ghz.
If its older software, its highly unlikely to take advantage of multiple cores.
If its a 3D PC game, your video card might be much more important.
