Ahh, there is vid, indeed there is.
With a 64bit CPU you don\'t have to split the instructions for longs and only have to split them into 2 instructions for longlongs...
Praticaly EVERY 3D GAME uses math calculations using LongLong ints and 64 bit floating point numbers.
Also the adressing space of a 64 bit processor is twice as big as the adressing space available on a 32 bit processor. what does this gives us? You don\'t have to swap pages as many times as you need to on a 32 bit processor.. which means less swapping because there\'s more space to hold memory pages which means lower time losses due to pagination.
Even though games aren\'t "prepared" for a 64 bit procesor, i can guarantee you that you\'ll get about 30% improvement in speed/loss of heat running quake3 on a 64 bit processor.
So how does this help a OS or application.. Even a single floating point calculation ocupies 64 bits. What the system does is that it breaks it down into the biggest chunk that it\'s possible to insert on a registry, it doesn\'t break it automatically into several 32 bit instructions, it queries the cpu to know how much adressing space is available
So.. if you\'re using a 64 bit processor, the CPU returns 64 bits as an answer to the OS query and the OS breaks down the instruction into several 64 bit chunks...
What winXP 64-bit edition does, is that it takes advantage of those 64 bits directly. the memory pages all have 64 bit adressing space (which means larger pagefiles) with 32 bit pagefiles on a 64 bit processor you have smaller pages but you can fit more into the memory (x2) without having to swap as much as a 32bit cpu.. which gives you aproximately 80% of a 64bit OS performance in what comes to swapping processes, which means a 64bit cpu will perform very well on a 32bit OS.

Well, that\'s it, dual channel, and I have noticed, actually, a great change in performance: the system is much more fast now. I\'ve 2 Kingston 512ddr 133mhz.
I\'m using 2 sticks of Kingston Mem, 1 pc2100 (266) 512meg and 1 pc3200 (400) 512meg. When you run 2 different speed chips they defualt to the lowest one. I\'m getting another 512meg pc3200 tomorrow, so i\'m giving the 266mhz chip to my gf.
