Currently Im benchmarking the HD 6970 but I have some problems with. Mainstream you say Yes, this card is a mainstream card, though it is on the high end side of mainstream. You will find the best performanceper dollar while still having great 1. P performance in this range. Here are some things to keep in mind 1. Fury X is 1. 1 faster on average than the 3. X 1. 08. 0Pand 1. X 4. K yet cost 3. Fury X is 1. 6 faster on average than the 3. Pand 2. 2 faster on average than the 3. When considering a GPU purchase, please keep overall performance, price, and priceperformance ratio in mind. Below is a chart that I will be updating whenever major price changes occur. WHICH CARD IS FOR ME Lets start with some generalizations about each brand that I have simply made for myself based on user information. Here is a beak down on what I have seen with these cards so far. Keep in mind that aesthetics were not considered, as that is a personal preference. XFX Full cover waterblock available. SEE COOLING SECTION These are good clockers usually, and cooling is good for core, but not stellar, and VRM cooling has been revised to stay much cooler than early versions of this card. SapphireSEMI COVER waterblocks are now available from Alphacool Not to mention this card has excellent air cooling. Require 88 pin connectors versus 86. Some would prefer that, in hopes of obtaining higher OC results, but unfortunately OC results so far on the Nitro and Tri X are only mediocre good. Gigabyte No waterblocks. Well built card, decent cooling, but the voltage is hard locked, so expect clock ceiling to be very limited. Power. Color Offers full cover waterblocks, and also has excellent air cooling, but so far there have only been weak mediocre ish overclocking results. MSI SEMI COVER waterblocks are now available from Alphacool Stock air cooling is good but not great with regards to the core temps, but seems to be very good for the VRM temps. So far, these seem to have the best overclocking results. Most poeople hitting 1. Asus DCU2 Full cover block available. Not much info on these, but theyappears to use the same cooler as the 2. I have seen very few purchasing the Asus card. Overclock results seem to be average so far, but have very little data to make a general claim. Serial Pic Programmer Software'>Serial Pic Programmer Software. Asus Strix Unsure on waterblocks with these. Very little OC information, but from what I have seen, they are average. Probably in line with Sapphire when it comes to binning. And now the details and pictures. To overclock these cards, one can simply use the Overdrive function of the Catalyst Control Center, but for anyone wanting to overclock these cards outside the constraints of factory voltage, you will need a third party application. I normally recommend one of the following utilities Keep in mind that these utilities, to my knowledge, will work with all manufacturers cardsThen, there is also Asus GPU Tweak, but it is not known if this utility supports all 3. Asus. It can be found. HEREAfter gathering more overclocking information from new members, and based on my personal experience, it is apparent that these cards, while capable of reaching respectable clock speeds, are not capable of much higher overclocks than were achieved on the 2. X cards. At this point, most members are able to reach speeds of 1. Many members are finding themselves in the 1. These results are inline with some of the better clocking 2. Ive seen, but not congruent with some of the golden samples I have seen from the 2. MHz using more than 1. MHz at all. It appears that while these cards clock higher than the 2. MORE voltage. right Well actually, heres why. With the improved low leakage silicon used on this series, we are getting higher clocks within a low to moderate voltage range 0 1. This causes these chip to exhibit higher temps also. They all seem to get to a stopping point around 1. MHz on average, and then they are simply done Ive not seen any stable over 1. Even in spite of how cool you get them, and how much juice you send. These characteristics are very similar to AMDs improved process to their Vishera family of CPUs. This improved process has major advantages for the average user who does standard overclocking on air using no or mild voltage bumps, however this series may not be the best option for extreme overclockers who plan to put their cards on custom water loops and use high amounts of voltage. Definitely stick with modified 2. Lightning Matrix for that kind of stuff I had theorized early on that these cards would clock much better on water, but as more water results surface, we are still seeing these cards run out at 1. MHz. Its not to say there arent some samples out there capable of doing marginally better, or who knows, maybe a lot better. MHz or less Hawaii cards. Now, its not to say they WONT run at higher clocks, but you wont get better performance, as the cards just tend to give deminish returns at a certain point. This is not due to temps or throttling or power either, its just simply an unhappy card after that point. I have personally benchmarked my card at 1. MHz1. 75. 0 using 1. Mhz at 1. 00mv. And even 1. MHz at 1. 00mv only scores a few more points Fire. Strike graphics score than running at 1. MHz on 6. 0mv. NOW, the non debatable, and good news for all overclockers. The Memory ICs are hands down, great clockers on this series, and users are finding themselves in the 1. I too was able to break the 1. MHz mark, but only with the addition of AUX voltage. Anyone finding their cards memory to be capping at 1. MHz may want to try 2. Digitizer Ex Software. AUX voltage to achieve a higher clock speed. For members who are overclocking their cards, and would like their results to be reported on the owner spread sheet, PLEASE include your clock speeds, your voltage offset used to achieve them, and a benchmark for some verification. More to come on votlage, temps, cooling, etc.
