Pros: Amazing OC headroom. Great space heater.
Cons: Power consumption was way too high for my liking. Temperatures were also ridiculously high despite the cooler on this product supposedly being great. Product was supposed to run off a 500W power supply with two 6-pin power connectors, but the product I received was rated for a 600W power supply with one 6-pin power connection and one 8-pin power connector. The product I received used a 7970 board, but I wanted a 7950 board. My power supply is rated to only 500W, and I have an aversion to power inefficiency.
Other Thoughts: I returned the product (thank you newegg for the return) and got a Sapphire 7870 instead. Power consumption and temperatures are much better now.READ FULL REVIEW
Pros: Low profile. Low voltage. Low power consumption. Great OC ability. I'm running these at 1866MHz with 9-9-9-24 primary timings. Great price. No need for fancy memory heat sinks or fans.
Cons: I can't seem to get these to work at 2133MHz or higher. It seems as though 2000MHz is the highest I can get. I suspect this is because my MB is limiting me, so it is probably no fault of the memory.
Other Thoughts: Samsung is a great company. Every Samsung product I have owned has been great. Samsung, if you are reading this, thank you for creating great products!READ FULL REVIEW
Pros: Performs quite well. Very quite. Excellent power efficiency. My core can OC to 1160 MHz with stock voltage of 1218mV. After flashing in a newer BIOS with higher voltage of 1243mV, the core can OC to 1200MHz. I was able to edit the BIOS with a hex editor to make the OC permanent (i.e. no more need for OC software). 3dMark11 score is around P8900 with 13.1 drivers. I believe this beats gtx 580 and gtx 660 ti at stock settings, and comes close to a stock gtx 670. Maximum OC for the core is 1275MHz, but this requires further voltage and is not 100% stable. Maximum 3dMark11 score is around P9200. Very cool with a maximum temperature of 69C when OCd to 1200MHz and stressed with Furmark. Sapphire makes excellent coolers.
Cons: Not as fast as 7950, as 7950 has much more OC headroom. My memory can OC to only about 1250 MHz before error correcting comes into play and introduces a performance hit. I keep the memory at 1248 MHz. I lost the OC lottery with the memory, as others seem to be able to OC the memory to 1400 MHz or so. I had a Sapphire 7770 with memory that could OC to 1350 MHz before error correcting came into play and could OC up to 1600 MHz without crashing. I was hoping for similar memory with the 7870, but no luck. The low OC on my memory is holding me back. I think I would be able to get a 3dMark11 score of around P10000 if the memory could OC to 1450MHz without error correcting coming into play.
Other Thoughts: Now that GTX Titan has been released, my card looks like a performance wimp :-( I wonder if AMD will be able to answer.READ FULL REVIEW
