Video Card, Power Supply, And Case
Graphics Card: Galaxy GeForce GTX 780 Ti
Our last enthusiast build featured two GeForce GTX 770 cards in an SLI configuration. Interestingly, the lowest-priced GeForce GTX 780 Ti on Newegg as I write this sells for the exact same $660 as last quarter's dual-card setup.
When I originally wrote down the parts for this build, Galaxy's offering was the lowest-priced option on Newegg. It's now sold out, but you get the idea: we're looking for the most affordable 780 Ti available.
We expect Nvidia's flagship gaming card to demonstrate more more consistent performance, though I'm accepting of the fact that last quarter's SLI arrangement will probably be quite a bit faster, particularly in Surround resolutions. Then again, the GeForce GTX 780 Ti lets us get away with a less beefy power supply.
Power Supply: Corsair TX650 650 W PSU
Using a single 250 W graphics card allows us to step down to Corsair's 650TX (from the 750TX we used last quarter). At $90, this is the reliable power supply that we usually favor for the mid-range enthusiast-focused machine.
Case: NZXT Phantom 410
The NZXT Phanom 410 was the only case to receive Tom's Hardware's Approved recognition in Thomas' Five Gaming Cases Between $80 And $120, Reviewed.
For that reason alone, I am giving the enclosure a nod in my System Builder Marathon box. It's an especially attractive option now that the $100 price tag doesn't directly take away from the price/performance calculation run on day four of the series.
