Scan 3XS Vengeance GTX680 Z68 OC System Review
Taking all the hardwork out of your hands the Vengeance Z68 OC earns its name with a 4.7 GHz overclock on the 2700K. You certainly wont be lacking for processing power.
The memory is of the 'lots of capacity, average speeds' variety. Considering that to get 2133MHz memory of this capacity you're forced to pay extortionate prices or use four sticks, and also how well the Z68 chipset handles memory bandwidth, this isn't as much of a detriment as one would expect. At least you've got the option of filling the other slots if you want, or dipping into memory overclocking yourself.
So what does all this mean in terms of the coarse Windows 7 rating? A very fine 7.7, with 7.8 for the memory and 7.9 for the graphics and storage. You certainly wont be wanting extra desktop performance
