4th gen motherboard

not sure if there is a "best" as there are quite a few which work very well.

what kind of options do you need?

the asus maximus vi hero has quit a few features for $199... i've seen it on sale for a bit over $180 with some deals going on in the past.

of course to stay under that budget there are quite a few other ways to go... i would have a look at asus first.
