Don't listen to Kwaad. AMD CPU's are fine, he's probably just an intel fanboy. C2D ftw right now, but the 4800 x2 or above is still a sexy beast.
You also don't _need_ a DX10 card as there are VERY FEW GAMES THAT SUPPORT IT OUT RIGHT YET. However, it's good for the future and an excellent investment so you should go that route.
Also, a PSU may or may not fry your system. If the PSU fails, it doesn't automatically mean it'll fry your entire system. If the battery in your car is fried, does it kill the rest of the car? Case in point.
Another also, airflow is important, but it's not as dangerous as Kwaad makes it out to be. Just get a PSU with a bottom exhaust fan and that'll help with heat transfer.
