No. Like theman said, the A64 Venice 3000+ retails at around $150, and you can pick up a 3200+ at about the same price at Ewiz. You would need a new mobo for sure, maybe new RAM and a new video card if you wanted to go the PCIe route.
If you overclock you should be able to get a 3000+ to at least 2.4GHz and this will give you a significant (20%ish at least) increase as far as I am aware.
You can see what I have running now in my sig. In the near future I will be upgrading to a A64 Venice 3000+/3200+ and when I do i'll be making a thread about it and the performance increases regarding how it 'feels', benchmarks and gaming, so watch out for that and it will hopefully give you an idea about the benefits. I am simply getting a new mobo, RAM and HSF whilst keeping my AGP card.
There are plenty of articles around, search google, with benchmark comparisons regarding the older AXP Bartons and the newer A64's. (I would find some for you but am short on time).
edit, just saw your previous reply - Hehe, in answer to your question then - No.
