ALL motherboards have problems.. Even the $350 Striker (which just so we're clear is a big no-no.) And I don't know which reviews you've been reading, but don't take Newegg reviews with anything more then a grain of salt. 95% of Newegg reviewers are clueless. Read reviews by pros from sites like AnandTech and sites like that. I will guarantee you that no sensible pro review won't have any cons for any board. The DS3, P5B-E, P5B-Deluxe, P6N etc. are all some of most widely used and praised by people that know what they're doing.
The Tuniq Tower is one of the favorites. Thermaltake Big Typhoon, Scythe Infiniti/Ninja are some other. The Zalman 9700 also looks awesome but will offer a tiny bit less cooling then others I've mentioned.
Again, you would be better off with the 520W Corsair and make sure you have some nice speakers or headphones for that sound card
Edit: Posted a few seconds after your last one... Doom3 will max easily. Piece of cake for that system. And make sure the hard drives you get are Seagate Barracudas with 16mb cache. Most people prefer Seagates to other brands.
