Application Performance
Given that the processor and memory performance is almost identical across the LGA1155 boards we've tested, it comes as no surprise that the Gigabyte Z68XP-UD3iSSD had a virtually identical showing as the Asrock Z68 Extreme4 in Excel 2010.
We find similar results when testing with Adobe Photoshop CS5. However, when using these programs, it is apparent that the Core i7 2600K has a massive performance advantage over the Phenom II X6 1100T – though that's hardly a secret.
When testing WinRAR compression performance, we found that all three LGA1155 motherboards delivered exactly the same results, taking 96 seconds to compress a 700MB 720p HD file.
