I would go with the ASrock board personally. I only upgrade every few years so the Gen 3 appeals to me. If you upgrade more often then either would be fine.
Those prices listed for both are terrible though. Seems like the prices for both are around $169 now.
If you live near a Micro-center they have an i5 2500k/gigabyte combo for $270, if not... I heard of NCIX matching the price. Might be worth a shot.
