X97 series are gaming series chipset. The Z97 is also good. since u are getting the X79 at the same price, then with the X97 chipset.
There isn't such a thing as a "gaming" chipset, it's just both chipsets have a lot better features set than they're budget friendly counterparts.
X79 has quad channel memory support and lga 2011 support, however it is getting old, i'd wait for X99 to come in September.
Z97 is a lot newer and has support for a lot more things, like M.2 SSD, Sata Express, and other features you won't find on X79.
And btw, don't get a quad core for lga 2011, only get lga 2011 for hexa core cpus, since any of the haswell i7s will beat ivy bridge e quad cores.
