Reviewers have mixed opinions, as befits a healthy blogosphere, but the low-power 7750 generally comes off slightly better, especially for those looking to build a budget or HTPC rig. AnandTech likes the power-to-performance ratio of both cards, but dislikes the price-to-performance of the 7770, noting that the older 6850 still offers more in this respect -- at least for gamers. HotHardware concludes that AMD might have "technically" priced both cards "just right," considering how they stack up against NVIDIA's GeForce GTX560 and 550, but in practice those NVIDIA cards deliver a lot more punch for just a few extra dollars.
