As we jump into the benchmarks, bear in mind that this quarter's System Builder Marathon PC features the same CPU used last quarter. The most significant change involves the graphics subsystem, which, again, features a second GeForce GTX 770 graphics card. Expect very similar results from the host processor and big gains in gaming.
Surprisingly, the Cloud Gate test result (in red) barely changes, although the raw graphics score nearly doubles as a result of the SLI-based configuration I'm using this quarter.
The PCMark scores change very little, though last quarter's build actually wins when we overclock it (this isn't something I would have expected).
When it comes to storage, though, the new machine's Samsung 840 Pro SSD demonstrates a slight advantage, though you'd be hard-pressed to identify it in the real world.
As expected, Sandra's Arithmetic module yields almost identical results from the two Core i5-4670K CPUs we're benchmarking.
Sandra's Encryption/Decryption workload is memory bandwidth-limited on platforms with AES-NI support, so the previous build's lower memory data rate hurts its outcome. More curious is that this quarter's $1600 PC fares better than we'd expect in the hashing performance test, which leans on the host processor.
