Update to Closed Loopy Ghost build. Retired my dual 580s with a single EVGA GTX980 Superclock. Re-engineering the build shaved about 10C off of the CPU temps now that h80i is properly configured for push/pull. 4.5Ghz is a possibility, but I will likely wait for a Broadwell chip as a replacement.
After the Broadwell upgrade, a new 144Hz monitor or 4K, second GTX980, and likely custom water cooling.
Update Second EVGA Superclock added. Temporary installation for baseline testing. Following components waiting for installation.
