This build is an upgrade from a pc which was built in 2011.
The old pc before this upgrade was using a GTX 550 ti, Intel Stock cooler and a CoolerMaster elite 310 case. What I did was add a new graphics card, new case and a new corsair liquid cooler because the i7 was overheating when it used the stock cooler.
Why GTX 770 and not GTX 970? I used the GTX 770 because the gpu was already purchased from a different build.
