Hot Hardware published a review on the Maingear Rush With Radeon R9 295X2 CrossFire
A quote from the article:
When we reviewed the Maingear Epic Rush a few months ago, we found its performance jaw-dropping, and thus we expected the same out of its sibling, the Maingear Rush. However, these are different systems with different configurations on board. For instance, they have different CPUs--the Rush we're testing today has a newer, more powerful GPU configuration, and Maingear approached storage on the two quite differently as well.Maingear Rush Review With Radeon R9 295X2 CrossFire @ HotHardware.com
What both systems definitely do share is high performance and impeccable build quality. The Maingear Rush is a top-shelf system with killer components; there are no compromises here, and no concern for the final bill either...
