Pros: With no voltage increase I could squeeze 1228Mhz core and 6408Mhz memory completely stable. It ran 1163Mhz core and 6008Mhz memory out of the box. Most of the time it stays below 64C while gaming, synthetics and crypto currency mining bring the temps up into the mid 70's. I can barely hear it over my Noctua fans while gaming. It is audible when under a tougher load such as crypto currency mining or Kombustor. Still quieter than my old HP desktop. Runs BF4 at 90+ fps @1080p Ultra 4xMSAA Skyrim 60 mods it never drops below 60fps (Vsync is permanently enabled) @1080p Ultra FXAA Assassins creed black flag at about 60 fps @ 1080p Ultra FXAA PhysX Medium. Far Cry 3 at 75+ fps @1080p Ultra 4xMSAA Just for fun I will through in Minecraft benchmarks. Runs Minecraft at 1200+ fps Max settings.

Cons: The card is very long and case compatibility is a very real issue. I had to remove one of my case fans to install it. I don't have 2

Overall Review: This wasn't a problem for me but it requires two 8pin PCIe connectors from your PSU. So make sure your PSU is compatible. My case is a NZXT Source 530. Cpu Intel i5 4670k Mobo Asus Maximus VI Hero

Pros: They run at 2133MHz at 1.6v(Slightly higher voltage than advertised) totally stable no issues. Fast Look nice, fit into my color scheme. A steal for the price I got them for $124.99 The heat sinks have a real solid build quality. Can hold 2133MHz stable even with a 4.7GHz overclock on my i5 4670k (3.4GHz@stock).

Cons: It was kind of hassle installing them they were a very tight fit in my MOBO's ram slots compared to the Gskill ripjaws DIMM I have. Despite the tight fit it was only a slightly annoying.

Overall Review: You will have to go into your bios and set up your Dram timings and speed or your XMP profile. It defaults at 1600MHz if you don't do this. Its not really a big deal just takes a few minuets and is really easy. I have an ASUS Maximus VI Hero Lga 1150 MOBO, i5 4670k, H110 water cooler.
