Both your CPU and your motherboard are a bit out of date. You may wish to replace them with these:

Mobo:

Also, do you plan to overclock? If so, you should get a CPU cooler such as the Cooler Master Hyper 212 Evo. If not, it's likely not worthwhile to get a -k model CPU. Given that you had a -k CPU in place, I assumed that you wished to and selected a Z77 motherboard. If not, you can save money by using a B75 or H77.
