After almost 7 years of gaming exclusively on consoles, and almost 10yrs since the last time I build my own PC (I have had laptops since then), I decided to build a new main machine with good gaming capabilities. The machine is mainly used for gaming (mostly First Person Shooters and racing games), video encoding and media center.
I decided to go with the i7 3770K CPU because I also do a lot of video encoding, and while gaming does not take any noticeable advantage of Hyper-Threading, video encoding does. So far I have overclocked the CPU to 4.3 GHz. Ran a few stress tests with AIDA64 and Cinebench, and so far it has been very stable. Will see how it goes in the long run and report back if there are any issues or if I decide to dial it up or down a bit.
As for the heatsink, I know the thing is massive, but I was surprised to see it kept my CPU temps in check even after overclocking the CPU to 4.3 GHz. I'm not an expert in overclocking by any means, but I was expecting the CPU to run at a bit higher temps. I replaced the stock case fans with other 120mm fans with higher pressure and rpm ratings than the stock, so it seems the added airflow and heatsink are working properly to keep temps at safe levels.
I decided to do a test-build before putting everything in the case to make sure it POSTs properly without hardware errors (2nd to last picture). While I had absolutely no trouble with any parts, I did noticed that the BIOS was reporting about 1,300 MHz as the RAM frequency and had to manually set it to 1,600 MHz. MemTest completed successfully without errors, SSD is working properly and blazing fast, Video card have handled my games at maxed out settings with no trouble.
Overall I'm very happy with the build and I feel I will have this machine for quite some time.
