There are 2 types of Athlon users, I guess :
1) Those who need the FPU power, or those who want to support the underdog, or those who want to actually get benefit from DDRSDRAM, or those who want to overclock above 1ghz, or those who want a chip that is only a few pecent slower at worst, and 30%+ faster at best, across the wide range of programs available.
2) Those who were Intel-only users and got an Athlon for price-reasons only, but well and truly want Intel-inside again
I guess by this message you know which I am.

Hint : 3d-rendering is one of my hobbies.
In all serious though, this is great news for users #2. Maybe not such a good thing for AMD though, if Intel is finally taking them seriously enough to cut into their prices.
