AnandTechTom's HardwareGuru3DTechPowerUpPC PerspectiveIn terms of raw price/performance, it's not the greatest deal (assuming the Radeons stay around MSRP), but it performs quite well in terms of power consumption and heat dissipation. What makes me really excited is that it performs as well as it does while not requiring a 6-pin PCIe power connection. That will make it a great upgrade for OEM machines with weaker power supplies. I can see myself making a lot of recommendations for either 750 to people looking for upgrades.
The previous fastest PCIe slot-powered GPU that I know of, the Radeon HD 7750,
gets spanked by the GTX 750 Ti. Granted, the 7750 was substantially cheaper, but I've seen a good amount of people here ask what the fastest GPU is that they can stuff into their prebuilt box without having to replace the power supply. They now have two new options. The GTX 750 is much closer to the 7750 in price, and still beats it by a large margin.
Having said all of that, there's a few downsides. The drivers still seem to need some work, as evidenced by video decoding/HTPC testing. I was disappointed that the full DirectX 11.1/11.2 feature set wasn't implemented, as that would have potentially spurred developers into migrating to it more quickly. And, of course, the lower (theoretical) price/performance ratio compared to the R7 260X/265.
Overall, it's a bit more than I was expecting from a new architecture on an existing process node. I'm really interested in what Maxwell does on 20nm, as well as GCN 2.0 (assuming that's what it's called).
Oh yeah, it overclocks quite well.
