I think it was "ought to be enough" though.  

I think Groggy had it in his sig...

Before anybody starts talking about how little 64bit cpu's actually increase performance, let me tell everyone what 64 bit mode will actually bring to the table over the Opteron/Athlon64 32 bit modes:

1) more registers. This will get us fair performance increase from the start, as compilers will have more registers to work with when doing calculations on multiple pieces of data.

2) support for larger system memory sizes. This won't help you in video games, but it will help you doing high end photoshop, and other applications (provided you spend the money to get more memory put into your system)

3) native operations on 64 bit data. Typically, when someone wants to do operations on a 64 bit integer in a 32 bit CPU, you have to split up the work in software. Now with 64 bit registers, you will be able to do operations on 64 bit integers in the same time as it takes to do the same operation on a 32 bit integer.

4) when using native 64 bit mode, certain legacy instructions of x86-32 are depreciated. This is a cleanup for the x86 ISA, which in the past has contained literaly EVERYTHING that the previous generation of CPU supported. AMD's x86-64 ISA eliminates these legacy features and moves them into firmware emulation (don't worry, it won't degrade any modern 32 bit code, just terribly outdated stuff from the 386 days, which doesn't need 2GHz of power in the first place)

On top of these performance enhancements that 64 bit mode brings you, you get all of this just because you are using AMD's Opteron/Athlon64 CPU:

1) Dual channel DDR Memory interface, with memory controller on the die of the CPU. This reduces latency and improves memory bandwidth so dramatically that even Intel's off die memory controller can't keep up (this is why video games are so much faster on the amd64 platform than on athlon-32 platform)

2) HyperTransport bus to the south bridge, which will give high bandwidth access to the PCI bus, PCI-X, and other IO intensive controllers. Eventually AGP slots will be phased out for PCI-X slots which will be universal for both video, and other devices.

3) when using multiple CPU's in the same system, the new AMD-64 platform gives you dedicated memory bandwidth to each CPU installed. On the intel and athlon-32 platforms, all the CPU's in the system shared the same memory controller which runs either single or dual channel DDR anywhere from 266MHz - 400MHz.
