Just listen to me mate.
Are you going to oc ?
(Regarding OCing in this mobo, i heard from some TE members that this mobo is not suitable for that, but m not sure, since i dont know much about OCing and havent tried that.
If you are not going to OC just blindly go for asus m3n78em. Its a very very excellent fantastic motherboard with good stability , build and lots of features. I am enjoying this mobo.
I am having an old PCI yamaha ds-xg sound card with very excellent sound clarity almost 8 yrs old. Its working like a charm in this mobo without any issues. I absolutely agree that NVIDIA is known for its excellent compatibility....
If you want quality then ASUS is the best bet. This motherboard has only 2 PCI slots. If you want 3 PCI slots, there is M3N-H-HDMI which is also a good option, but the price will be 5k+.
But if you are very concerned about the A.S.S of ASUS, then its upto your choice since I have read many negative reviews about RASHI.
