AMD isnt as crappy as Kunckles post would have you believe. Performance gain to Intel is 20% about. Becides, processors have become so powerful that you'll never use the full potential of a lot of the high end chips from both compaines.
Yes, Intels processors are better for now, but this is intels newest line, AMD hasnt released their new architecture yet (A DDR2 controler doesnt mean new architecture), so Intel is just king by default. We'll see what happens when AMD's new chips come out. Maybe Intel will still be king, maybe AMD will again become king.
Not to bash Intel, their new Core2 chips are great. I just didnt think that was totally fair to AMD.
Onto hard disks: Size for a disk is another preference thing. And as for RPM's, some people hate load times and a 10K Raptor would be their cup of tea. The HDD is currently the slowest part of any computer. Thats where your bottlenecks will always be. Personally, on my gaming machines, I can fill up 120GB easily with the size of some of these games. And in my job, I can fill up a 320GB drive in no time
Hooray graphic design!
Each part you get through Newegg is warranted. If something breaks you just go to the company that made it. Computer repair isnt hard.
