The vast majority of the bells & whistles these days are for game playing.
For normal home use just about any current desktop computer motherboard is sufficient.
The one item to look for is a large amounbt of memory. Would say 6 or up.
Another is sufficent UBS ports as scanners, printers, keyboards & mice, external drives be they thumb, zip or hard usually require these.
Another is a large power supply as each USB port draws current.
I personally prefer two DVD drives as it easier to transfer data back and forth but a single works fine.
Basically I am saying don't get caught up in all the this and that if you are not going to use it.
Again, just my opinion.
Wishing all enough,
