I just have a few questions for you:
#1 - Is this a good Over-clocking/Gaming Spec?
#2 - What estimated clock speeds could I reach with this build?
#3 - Would you change anything?
#4 - Would you choose XP Pro over Vista Home Premium?
#5 - If anyone has a similar build what benchmarks are you getting? And are they impressive? i.e. PCMark / 3DMark etc...

All comments are very much appreciated I never fully understood just how much time and effort it took to find a good spec'd Gaming build so i'd just like to thank everyone that has been kind enough to reply to my threads and help me on my way to my first build this will also be my first overclock so I hope you nice folks can help me out as always!

Reason I'm posting here to is to see where or not it would be worth the upgrade to this board:

ABIT AW9D, I975X, Socket-775, SATAII, Silent Otes, GbLAN, DDR2,ATX, 2xPCI-Ex16. It comes with the guru technology and the only difference between this one and the AW9D Max I can see is that it has a smaller heatsink and fewer SataII slots to name a few.

Please share your views on this?

Thank you.

Ok I think i'm going to splurge on this one and get the Abit AB9 QuadGT problem solved.
