You don't need to spend $30 on a heatsink and fan... and I've never had any problems that were related to my processor that would have been different if I had an Intel processor. I've never had an AMD processor fail (not my 166 Mhz K6, not my 333 Mhz K6-2, not my 700 Mhz Duron, not my 1.2 Ghz Athlon, not my XP1700 Palomino, no my XP1700 T-Bred A, and neither of the XP2500's that I've had), although I do have a dead 486 Cyrix, and a dead 233 Pentium that I acquired from other people for free.
Again I'll say... if you have $200 in your pocket, you can't even begin to buy a worth while Intel CPU/motherboard combo. But you can get a damn good AMD CPU/motherboard combo for $200.
