I'm not much of an Intel person, however for a heatsink I will recommend the Vantec Aeroflow heatsink, I have one on my Athlon XP and it's very quiet and keeps it extremely cool.

According to that review, Asus or MSI 875 neo (

I'ld lean more towards the MSI board (lower cost and I'm biased against Asus from previous dealings)
Those are the top 2 manufacturers of 875 boards, Abit is very low on performance (lowest of all boards reviewed.)
