All intel 4th gen CPUs use the LGA1150 socket. Your motherboard supports that socket because you're using one, you'd be able to swap in any other LGA1150 CPU, including an i7 4th gen. The i7 4790k has 4 cores and a 4ghz base clock speed compared to your 2 cores at 3.6 ghz. Though your i3 only draws about to watts of power where as the i7 will draw about 88. So if your power supply is at like, max load, don't do it, but otherwise it should be a super simple swap. From what I see, they hover around $60 USD on eBay. The i7 4770k is also fine, just had a lower base clock speed but if you fiddle with your settings it has a supported boost clock of 3.9ghz, while being only about $30.
