Graphics Card

ZOTAC GeForce GTX 980 Ti AMP! Extreme - $669
A single GeForce GTX 980 Ti should be able to cope with 2560 x 1440 pixels approaching 120 Hz refresh-rates. The best GTX 980 Ti of the lot is ZOTAC's AMP! Extreme. It offers the highest clock speeds out of the box at a premium of just $20 over reference. Its scorching fast GPU and memory are mated to a meaty triple-slot cooling solution that can idle at 0 dBA and isn't too loud under load.

Storage

Main Storage (SSD) – Crucial MX200 250GB - $94
Crucial's MX200 remains the best combination of performance and price-per-gigabyte you can find in the market. Faster M.2 based NVMe SSDs are still 50-100 percent more expensive. Hopefully, Samsung's 950 Pro will changes that, but unfortunately, it's not available yet. $94 for a 250 GB drive with top-dollar SATA SSD performance is a heck of a bargain. Affordable M.2-PCIe SSDs are yet to make their mark, and their price-per-GB figures remain double those of high-end SATA drives.

Additional Storage (HDD) – Seagate 7200.14 Barracuda 3 TB - $89
3 TB hard drives are getting cheaper every day, and your build isn't complete without an HDD to cold-store the games you aren't playing. At $89, the Barracuda 7200.14, as its name suggests, offers 7,200 RPM spindle-speeds (no variable speed trickery), a 64 MB cache, and AdvancedFormat hardware support.

Power Supply

Rosewill Quark 650W - $109
Rosewill has come a long way as a brand, from its origins as a cheap component Khajiit. Its Quark series of PSUs offer everything needed to qualify as high-end, beginning with 80 Plus Platinum efficiency, a large silent fan that only revs up under load, full-modular cabling, single +12V rails, four 6+2-pin PCIe power connectors, and a 5-year warranty to top it all off. A PSU with these specs is hard to find at $109.
