Conclusion: Performance Summary: The ASUS EAH4870 TOP performed as we expected it to for the most part. It, of course, offers a nice bit of extra performance over a Radeon HD 4870 with reference clocks while performing significantly better than a Radeon HD 4850, especially when the resolution and eye candy are cranked up. Furthermore, the EAH4870 TOP trades victories back and forth with our reference GeForce GTX 260. ASUS's "TOP" line of video cards never fail to excite.
Pros: Great performance, Factory overclock, HDMI 1.3 output (built-in multi-channel 7.1 surround audio over DVI-HDMI adapter), DirectX 10.1 support, CrossFireX support
