There are many advantages to having 64 bit vs 32 bit.

I dont want to hijak this thread and turn it into a 32 vs 64 issue.. but i believe it has merit in adresing the initial post because we are at a point where cpu tech is shifting between the two and it 'may' be sooner than later.
As you can see from reading the info in this link there are many benefits of the 64 bit platform. the 64 bit platform is also backwards compatible with 32 bit.
64 bit is an investment to the future. yes 32 bit will be around for some time however you wont have to change your hardware as 64 bit starts to become more mainstream. Designers wont stop forging ahead with technology and before you kow it 64 bit will be the in thing and software will be designed to be optimised for 64 bit.
I have just read that ARIMA released a turion laptop... so when the benchmarks come out then we can see the comparisons between the 32 bit and the 64 bit architectures.
For me, i am not one to keep upgrading my hardware too often.. i have better things to spend money on lol.. so when i buy, i buy the best at that time so i can keep it for as long as possible. and i believe the 64 bit is the best answer to what im looking for.
However, if you dont mind upgrading your stuff regular then that is fine.. it wont matter what you buy because you will always be at the front of technology.
anyway lol... thats my 2c worth

cheers.
