My intent with this build was to create a rig with plenty of performance and plenty of room for future upgrades while maintaining an efficient bang for my buck. I wouldn't call it a budget build by any means. Though there are plenty of rigs out there with far, far higher price tags. I would call it a solid mid-range build.
CPU: I went with the 4670K instead of the 4770K because my research led me to the conclusion that the advantages offered by the 4770K are not worth the price for me at this time. Since they both use the same socket and I can still use the same cooler, swapping in the 4770K in the future won't be too difficult if I find it necessary to do so. I chose the unlocked 'K' version so that I can OC if I feel the need. I felt the higher price was worth the greater versatility.
CPU Cooler: I am using a Corsair H100i for this build. It's overkill at stock speeds but OC is definitely in the cards for the future, the Haswell core runs a little hot anyways and cooler is always better. My CPU runs very cool with it, even when benchmarking. (see stats below and pics for screen shots) I did have one complaint.
The screws provided are too long. I'm experienced with liquid cooled builds so I knew to be mindful when screwing the fans to the rad and the rad to the case. If you are not careful, you will damage the rad with the screws if they extend too far, and these do. The screws that mount the fans to the rad are barely short enough, if you are very careful, you can secure the fans without damaging the rad. The screws to mount the rad to the case are so long that I had to use two extra washers (three total) to get the screws to tighten without running through the rad. Not a big deal but they could have included a few extra washers for you. I put the washers between the rad and the case to avoid clearance issues with the case fans. (see pics) There is also no word of caution in the instructions. I could easily see someone not familiar with building liquid cooling loops not realizing the danger and damaging their rad. Little details like that do make a difference.
Mobo: I went with the ASRock Z87 Extreme 4 because it has a good reputation, a good price, had the slot options I wanted and caters well to OC.
Vid card: I decided on the EVGA GTX 780 because it could supply more than enough performance at stock speeds and has great overclocking potential with the ACX cooler. I could also put in a dedicated loop and install a water block later if I wanted. I felt that the GTX 770 might not give me enough performance for future games and the 780 Ti seemed too expensive and overpowered for my needs. I can drop in a 780 Ti or a second 780 in SLI configuration easily enough in the future when the prices come down as newer cards are released.
RAM: I chose the Ripjaws X series DDR3 1600 because of its rating and price. I could have gone with faster RAM but I didn't feel that the performance increase was worth the price. I felt that 8Gigs was plenty for now but if I need more in the future, the ASRock mobo can easily accommodate.
PSU: 850w Cooler Master Silent Pro M. Primarily because I already had it sitting on a shelf, but also because it's a good quality PSU and can provide more than enough power to OC both my CPU and GPU. I may swap it out for a fully modular 1000w - 1200w unit if I decide to SLI in the future. Would have gone that route to begin with but this one was NIB, collecting dust on a shelf so...
Case: The NZXT 630 (Windowed Edition) A great case, lots of ventilation and options for cable management, and it looks really cool! My only complaint so far is that removing the front panel takes way, way more force than it should. The plastic was warping under my fingers and I still couldn't get the thing off. I finally took some pliers and pinched the tabs together and still had to use more force that I was comfortable with to get the thing off. The 200mm top case fans did not have enough clearance to accommodate the screws for the Corsair rad, but some neoprene grommets solved that issue (see pics) and should provide vibration absorption for the fans.
Sound card: Creative Sound Blaster X-Fi XtremeGamer Fatal1ty Pro. This is a legacy part from my old rig. It produces great sound and saw no reason to buy a new one.
Monitor: 24” Samsung 245BW Bringing over from old PC. 1920x1200 native res, 5ms. 1000:1 contrast, 400cd/m2 brightness. Never had issues with it saw no reason to upgrade.
Keyboard: and mouse are nothing special, they came from old rig and do the job.
Conclusion: This build has all the power I need, plenty of room to grow and came with a respectable price tag. It runs fast and cool and I couldn't be happier with it!
