Are there marked performance boosts when running an athlon 64 bit processor compared to a 32 bit processor with an equivalent clock speed and equivalent memory?  Considering I would have a middle-of the-road video card, would a 64 bit processor be worth the extra bucks, or would the card just be a bottleneck when it comes to gaming?

The 64-bitness of a processor doesn't mean anything. Everything that you run is 32-bit, so you're not using the 64-bit capabilities of the processor. It's just marketing, for now at least.

But why does it matter? The Athlon 64's are known to be the best processor for gaming, and it does indeed have a very good 32-bit mode. Forget 64-bit and get whatever you can afford.

A)  In order to take advantage of the Athlon 64's 64-bit capabilities, you need to run a 64-bit OS, like Windows XP 64-bit (still in beta, IIRC) or one of the 64-bit Linux variants.  Ideally, you also need 64-bit apps, of which there are very few.  So right now, as Raven says, the "64-bitness" of the A64 CPUs basically goes unused and shouldn't really be a factor in one's buying decision.

B)  It's meaningless to compare CPUs at the same clock speed; instead, you should compare their performance at the same price point.  And here, the A64 family pretty much wins hands-down, especially in games, except in a few areas where the P4 holds sway.

Bottom line: for a game machine, the A64 CPUs are your best choice, IMHO.  You may wish to hold out a bit for the PCIe-based A64 MBs to come out, if you want to make the switch to PCIe.  But otherwise, the A64s kick beaucoup ass.

IMHO, of course.  :wink:

Thanks for the input.   Since this is someone else's machine, they're kind of hot to trot, so PCIe will have to wait till some other time.  For basically the same amount of money for an athlon xp system I had priced out, I can go for a 64 bit system, 3000+ processor with mobo.  Because of a money cap, I'll have to stick with a 9600xt though.  From what I understand, the stock heatsink/fan that comes with the retail 3000+ is pretty decent. I think I saw something about that over at GG one time.  Any opinions on that  heatsink?

I'm using the stock heatsink/fan combo that came with the retail Athon 64 3400+.  It's a solid unit that does the cooling job just fine.
