I'm in...reference Sapphire 5700 XT with a full EK block. There are a couple of pics in my sig. I'm still tinkering with this build. I've switched back and forth between vertical and regular mount, and I'm playing with the OC. I ran it for a while at 2150Mhz and 1200mV, but I only had it at 915 memory. Now I'm running it at 2130Mhz and 1175mV, and memory at 925. My benchmarks were better with 2150 and lower memory speeds, but temps were quite a bit higher. At 2150, actual game speed was just shy of 2100 steady (usually around 2095 to 2099). At 2130Mhz, games are holding at around 2080Mhz, and I lose about 60 points in timespy, but temps are much better. I am still trying to find a sweet spot with best performance and sub 90c hotspot temps. My particular card is a good clocker, but terrible on temps. Before I got the water block, running furmark would hit 110 hotspot at stock clocks and 50% fan, in an open bench.
