The onboard graphics may be GREAT for an IGP, but still kinda' weak.
Its not for gaming, thats for sure. The MSI board is definately not an overclocking board either.
For me, I need a little SFF for my Dad, so I thought I'd try the MSI since there are no other boards to choose from. He won't need any gaming performance, and he won't need it for a few months, so I'll be able to fully put it through the paces.
I want to try the onboard driving a CRT along with my X800 XL to see how they work together, and see if I can live with a mATX board. I could end up making a few simple MCE rigs if its nice and stable platform.
I think you need to build your rig for today, the upgrade path may not look so sweet when you are ready to drop a 939 into that ASROCK board. Aren't there any decent overclocking 754 budget MB's? seriously, for gaming, you shouldn't be thinking less than 9700/9800pro at this point anyway.
