Hello
i want to know what i need to use 32 bit or 64 bit ?

My processor model is : AMD Sempron Processor 140 Processor 2.7ghz 64 Bit.

I use 32 bit .
I must use 64 bit ?
Will he work better (fast just processor) if i use 64 bit?
Have problem if i use 32 bit ? will he work slowly if i use 32 bit ?
Thanks
