I HAVE both Iwill and MSI, and tell ya the truth, Iwill is better. I have the following reasons:
1. Good case, good retention lock, better than MSI
2. Good craftsmanship, high quality and stability, same goes for MSI
3. Nicely laid out, adequate space between the socket and the jumpers compare to the lack of space on the MSI
4. Big ass capacitors, 1000uf compare to MSI's 100(150?)uf.
5. More voltage selections.
Overclocking has been just as good as MSI. It's worth the money, trust me.
