Even if you did wait for the next top of the line CPUs you have 2 problems
1) usally the first couple months of any CPU's initial release, they're are many considerations for Motherboards, chipsets, working drivers, and resolving issues.
2) By the time you get comfortable with your new CPU and all issue been resolved, 2 generations of new chips or new boards would have gone by.
Solution:
The only time your computer wont last you long, is if you are one of those geeks, who has to play that game that wont come out for another 2 months, but they garantee you need to "get that card" or get that Chip.
if you want something to last you for stuff like office, cad, basically anything other than hardcore gamming or DVD ripping, and the likes, anything 700-750 and over will suffice, given least 128 megs of rams, (256 is good but will only improve your game performance by 7%, where as it improve office productivity alot more, since those benefit more on multitaskin in the rams) , a 72,000 RPM Harddrive, preferably IBM's type of drives.
Get something that'll fit your budget, for example I have a Duron 800 on an Asus K7V, 384Megs of rams, 61G Maxtor 54000RPM , 10G , and 13G Harddrives, with a Geforce DDR, and SoundBlaster Live! Platinum, keep in mind some of the parts I still have might even be hitting a year old, but it still does me great.
Good maintance, and building keeps it alive, not shear speed, keep in mind CPU isnt a speed factor, you gota research for good motherboards, efficient rams, and most important of all, a fast harddrive since thats where most of your bottleneck can occur.
