Yeah, but can it equal my 2.75GHz P4 and PC1160 RDRAM?

LOL, that will be the day... Don't talk about your overclocked Athlon XP vs. a stock P4...that's not a fair fight. And I doubt that it beats the 2.53GHz P4 very often in the real world. Besides, overclocking is irrelevant in this thread, since he already said he isn't going to be doing any...
I think the best choice would be the P4, since they have a better long term future than the Athlon. AMD will not be producing any more high-performance parts for the Socket A platform. Intel, meanwhile, will stick with socket 478 until Prescott (.09um P4) debuts. Also, as time goes on, more and more applications will take advantage of SSE2, so you will see the P4 have performance increases as these optimized applications come out.
Not to mention that the P4 is WAY quiter and cooler...
