Rebooting
wait wait wait.. it is 610i also no Dual Channel support 

All though you have not asked for any advice but as a well wisher and a frnd, bro, stick with your Intel D946GZIS
D946GIS supports Dual Channel
would deliver better performance compare to 610i with single channel and there is no effect of the onboard VGA as u plan to run 8600 GT
as the D946GIS do comes with 1 x16 PCI-E Slot 
why would u chage the board ?? out of my understanding
its simply waste of that Rs. 2.8k
