Now for a mini update:
I decided that while i wait for a few more things to be manufactured, that I might as well create a little bit of a SLI Scaling update. For this mini 'review', I overclocked each GPU to the following:
These cards came overclocked to 1006mhz on the core. So I tried to get as much out of the core as i could, while maintaining stability. I think that my PSU held be back a little bit, as the second core wasn't 100% stable beyond these clocks. As well, the ram didn't respond as well as i would have liked. The 3GB per card however, provided plenty of headroom for what i want to play.
For each test, I used both stock values and the above attained overclock.
In regards to my testing methodology, the only synthetic benchmark i used was Heaven 4.0.
The systems specs are as follows:
CPU: i5 2500k (4.2GHZ)
2x4GB Patriot Viper Extreme 1866
60GB Corsair Vertex SSD (game drive)
2x Galaxy 660ti 3GB
Seasonic X-660 PSU
Each benchmark and game was played at 2560x1440.
The following settings were used: Each game/benchmark was done with the highest possible graphical settings. I'll break each out individually as i display. More games to be added as soon as i have them purchased :) Each test was conducted using nVidia 310.70 Drivers
As seen here, single cards were average around 19-20 fps, despite the overclock. While the SLI setup was 30-31 average fps. This reflects a 50% scalability on this synthetic benchmark.
Quality: Very High
Dead Space 3 didn't really test my GPU's like i thought they would. I guess that's something you can expect form a console port. Single cards ranged from 85fps stock to over 100fps when overclocked. SLI scaling took a hit as well. I think this has to do with lack of a SLI profile for this game. With SLI overclock numbers reaching just about 120fps. This would represent a ~20% increase when in SLI.
Anisotropic Filter: 16x
For this, i'm also including sourced GTX Titan #'s from a review site that bench marked this game at 2560x1440. I'm including these as this would provide a really strong value assessment to these to cards. This data is sourced and all credit for the GTX Titan goes to by Ryan Smith & Rahul Garg at Anandtech.
BF3 is where these cards shine with regards to my testing. Single Overclocked card tested at 44.9 fps. In SLI, these cards were able to pump out 84.7 average fps. This results in 89% increase. This is by far the best scalabilty I've seen through my testing. In comparison to the Titan, These two cards at stock, and overclocked beat it. Not bad for cards that on sale can be had at $550.00.
This conclusion needs to be prefaced by stating that the review is far from done. New titles will be added and I'll continue to push these cards hard. However, the biggest thing to take away from this is that when using the Titan as a base of comparison, these cards in SLI really shine. An 11% increase in fps at half the price of the Titan is nothing to complain about. When you take into consideration the kick ass cooler, and non-reference design Galaxy has a winning package on their hands. These cards compete with the best, at a fraction of the price. Probably the best value you can find right now.
If you guys have any questions or concerns please let me know and i'll be more than happy to address them :)
