If your not looking into overclocking get an intel motherboard they are the most stable for pentium 4 have not had a single problem with one. Now if your looking to overclocking later then get an Asus motherboard. The northwood, prescott are the cpu core. The architecture design. Prescott runs hotter and northwood runs cooler. below 3.0 ghz northwood is better after 3.0 prescott is better. Odd if you ask me.
intel D865GBFL is the motherboard you were looking at and its a good motherboard. If you want something with on board video get that. If you have a video card then get a d865perl.
