(random quotations are for readability) Not my first rodeo, but this IS the first build I've done for myself.
CPU: i7-4790 3.6Ghz: This is a great CPU, even if I won't use its full potential for a long time. Boosts up to 4.0Ghz when temps are low enough. With Hyper 212 EVO, max temps are very reasonable at 60C load.
Motherboard: Asus Z87-A: Yes I know, it's a Z-series board with a non-overclockable CPU, please put down the pitchforks. This is a great board with support for future SLI configs and more RAM as needed. The included I/O shield has some very sharp edges, and I cut my finger fairly deep while inserting it into the case.
Memory: Crucial Ballistix Tactical Tracer: Not that much more expensive than standard DDR3-1600. plus it has some badass lighting. 100% worth it.
Storage: Seagate Barracuda 3TB 7200rpm: I have a LOT of Steam games, so this drive is great, especially considering it was only $40 more than a 1TB drive.
Crucial MX100 256GB SSD: No matter what your price point is on a PC build, an SSD is a must. The MX100 drive provides excellent speeds at a reasonable price.
MSI GTX 980 Gaming 4G: This card is absolutely insane. I have a 1080p monitor, so for almost all games, I have to turn on DSR to not feel guilty about wasted power :) Skyrim at Ultra with 8 graphics mods can run at 4K downsampled at 58 FPS.
Overclocking: the GTX 980 was able to gain +172Mhz on the core clock and +744Mhz on the memory clock with no overvoltage, and still tops out at 70C in Valley Benchmark ExtremeHD. Average benchmark score increase from the overclock is about 14%.
Case: Corsair Graphite 230T: Great case for the price, 2 fans at the front + 1 at the rear means a positive pressure environment for less dust. fans are quiet at 50% via the fan controller, cable management was adequate, but the right side door didn't leave a whole lot of room for cables.
PSU: Thermaltake 750W Semi-mod: A cheaper alternative to the EVGA PSU I was originally looking at, this one is 80+ Gold and has enough PCI power for another MSI GTX 980 (2x 8-pin power each). Stickers are large and tacky, might be disruptive to color-coordinated builds. Cables are advertised as being easily managed, but I found them to be very stiff compared to similar offerings from EVGA
ODD: One of the cheapest optical drives I could find. Noisy, but does the job. Didn't need anything fancy because I rarely use DVD's anyhow.
Fan Controller: NZXT Sentry Mix 2: Worth every penny. Fan control is great, cables that aren't in use can be removed, and the color-adjustable lights match the orange on the case and front fans.
Conclusion: I'm really happy how this build turned out. My cable management was kind of crap, but good enough to allow adequate airflow. Amazing performance doing literally everything, although I'll probably use EVGA power supplies for builds where the budget allows.
EDIT #1: Updated memory clock number, currently stable at 7,748Mhz on driver 352.86.
EDIT #2: Not ok with CPU temps exceeding 80C, Cooler Master Hyper 212 EVO is on order, will update when it arrives.
EDIT #3: Cooler Master Hyper 212 EVO was a bit annoying to install, but temps are looking great. I can't find any stress tester (Prime95 need not apply for Haswell) that can push the CPU over 60*C.
EDIT #4: Got the memory clock up to 8 Ghz and still stable, going to stop there lol. This card is a breeze to OC and stays cool even on air.
