Hello, I'm looking into buying one of two older desktop computers however they both have different CPU set-ups and I'm not sure which is best one has 2 x Intel Xeon Nocoma 64bit Hyperthreading Processors @ 3.2ghz each = 8.32ghz capable of 64bit (2x3.2hz + 30%hyperthreading =8.32ghz) and the other has Intel Core 2 Duo E6600 Processor 2.4 GHz, 4 MB L2, 1066 MHz FSB, Dual-Core, Intel Virtualization Technology
Which is the best choice and is the Core 2 Duo capable of 64bit operating systems? thank you for reading.

Assuming hyperthreading improves performance by 30% is like assuming stapling pieces of paper is 30% faster if you don't have to look at them. It's only faster for certain applications. For applications not designed to take advantage of hyperthreading, it has been proven slower. Do you have an application in mind?
"Which is the best?" Well, that also depends upon the application. You're telling me the core2duo has 4MB of L2 cache; That poops all over the Xeons mere 1MB of L2 cache. The Xeons are going to generate A LOT of heat. They're also going to suck for power like a young gold digger sucks for money; You'll be paying for the Xeons by way of power bill for a long time ;). The Xeons will only be faster until their cache lines fill up or they heat up too much. Both of these are fairly dependant upon the application. Do you have an application in mind?
If you're smart you'll realise that "the best" is not well enough defined for us to provide a decent answer in this case; If you're stupid you'll choose to use those words again in the future without clearly specifying your intentions. The choice is fairly clear to me. New technology vs. old technology... hmmmm... Good luck with your choice.

Xeons work perfectly for gaming, the reason why they are not popular is because you can get more performance from a core i7 for less money than a Xeon
Xeons are generally more stable under higher temperatures and overclock better (probably because there pretty much under clocked from the factory)
and while they may have some optimizations, the performance benefits are generally very small (not worth the price)

Core 2 Duo is the best solution. it is newer and has a higher L2 Cache. It will also make less heat as it has a lower clock speed and smaller architecture?
The Benefit of the Xeons would be the higher clock speed and the dual channel cpu usage, which can make it faster. Check what types of RAM each has, and what chipset is on the motherboard as these are key factors too.
