The chaps over at HotHardware have posted a round up of GeForce GTX 285 video cards from Asus, BFG and Zotac. Recall that the reference NVIDIA GTX 285 clocks speeds are 648 MHz for the core GPU, 1,242 MHz for the GDDR3 memory and 1,476 MHz for the shader clock. The first card in this round-up is the ASUS ENGTX285 TOP, which sports clocks of 670 MHz, 1,300 MHz and 1,550, respectively. Next up, we have the BFG Tech GeForce GTX 285 OCX, the overall fastest card of this bunch, rocking at 702 MHz, 1,332 MHz and 1,584 MHz, respectively. Finally, we have the Zotac GeForce GTX 285 AMP! Edition, which boasts clock speeds of 702 MHz, 1,296 MHz and 1,512 MHz, respectively. As you can see, this should be an interesting battle to see unfold!

Out of the gate, we expected all three of the overclocked GTX 285 cards to offer a nice performance advantage over the reference NVIDIA GTX 285, and they all met that expectation. Thanks to its overall fastest clock profile, the BFG GTX 285 OCX performed the best by a small margin in most tests. The Zotac GTX 285 AMP!, with the second fastest clocks overall, offered the second best performance. That leaves the ASUS ENGTX285 TOP, which took a close third place but not by a significant spread. In a few cases, all three cards even performed quite favorably when compared to dual-GPU single card configurations like the Radeon HD 4870 X2 and GeForce GTX 295.
