I don't believe it will bottleneck it.
• NVIDIA® GeForce 6100 and nForce 410 Chipset
yes, it does. but lightly
while a full ATX with a performance chipset gives the best performance,
a micro ATX board with integrated graphics provides slightly less performance at almost everything. your board should perform about 2-8% slower. nothing like : hey, my 8800 gt gives 8600 gt performance...
entry-level boards are cost efficient. also, another version bearing the 430 chipset ( often paired with the nforce 410 ) gives more room to performance. and will only suffer about 2-4% performance loss...
if you stress your components intensively, you'll get the 4% and 8% loss... in idle, you'll only lose 2% and in some cases 0%... this is even true for interfaces. IDE, SATA, USB devices (not in the same ratio)
double check compatibility ( i mean number of issues you can find while searching through forums. ) some Matx boards will have power related issues with a capacitator leaking while plugging a top notch precise card...
a full ATX board is always a better choice while looking for top performance. check you PSU too because these video cards have a really high power draw. don't bother, your video card will not be bottlenecked more than your radeon was. it's an overall chipset performance we're talking about.
