Nope, no problems.
A 32-bit processor can only address about 3.5GB of ram natively, 64-bit
processors can address some incomprehensibly large amount of memory.
There's a technique which effectively extends 32 bit processors such
that they can address 64GB of memory. This requires support in both the
CPU and the operating system - linux kernels that use it are sometimes
often 'bigmem'. All processors have shipped with PAE support for quite
some time, and Ubuntu comes with it.
