I am aware of the button input lag on the Zowie FK1. However, there is evidence that this has been corrected with the newer 2015 models of the mouse. If you were to check this, you would simply look at the serial number on the mouse (might be on the bottom). You will see a series of numbers, and if you see "14" it is from the year 2014 and if you see "15" it will be from the year 2015. Models from 2014 have the latency issue whilst models from 2015 tend not to. Here is a video documenting a latency test between the Zowie FK1 2014 and 2015 models: As for your second question, I don't see any reason why the Zowie FK1 would have any issues running on a 1000Hz polling rate as that is a rate supported by the mouse, as per the system requirements page. It may tend to jitter on certain trackpads. As far as I am aware, there are no issues with the Avago 3310 sensor in regards to jittering.

The RX 480 is quite good, as it fares well against the GTX 970 (http://gpu.userbenchmark.com/Compare/Nvidia-GTX-970-vs-AMD-RX-480/2577vs3634) (which has a somewhat higher cost). However, at this time, I would actually recommend against purchasing the RX 480 GPU. The RX 480 was initially rated as a 150 watt card, but when tested, it was found that it used an average of 168 watts under load. After further testing, it was found that the RX 480 pulled from the PCI-E slot in the motherboard 90 watts, whilst the maximum of the PCI-E slot is 75 watts. This has even resulted in some PCI-E slots actually dying. Until AMD releases an improved model/version/fix to or of the RX 480 where these problems do not occur, I would recommend against purchasing it. Build safely. In the meantime, however, you could check out the GTX 970, 980, or 980Ti, which all have excellent ratings. Here is an good article on PCWorld if you are interested in reading more about the current state of the RX 480: http://www.pcworld.com/article/3091128/components-graphics/amd-promises-fix-for-radeon-rx-480s-controversial-spec-exceeding-power-consumption.html

First, why does the Razer DeathAdder Chroma advertise mouse acceleration? Isn't this something that gamers would dislike? Furthermore, I am not exactly sure what "ultrapolling" means other than the fact that the mouse has an "ultra" high polling rate. It does not mention variability in the polling rates. The Razer does, however, indicate a 10,000dpi optical sensor, which means that it could potentially have a DPI range up to 10,000. Moreover, I'm not sure what "Always-on" mode is. The Zowie FK1 does specify a variability in the DPI (400, 800, 1600, 3200) and the polling rate (125, 500, 1000Hz). From what I understand, gaming mouses generally tend to have a LOD of under 1.5. However the Zowie FK1 indicates that it could be potentially up to 1.8. This is important because if you are moving your mouse across the mousepad at a high velocity, especially in competitive games, it could potentially lift off of the mousepad at a height greater than the LOD (lift-off distance) and therefore stop tracking. Aside from the fact that many people also recommend the Zowie FK1, it also utilizes the Avago 3310 sensor, which is highly rated, whilst the the Chroma comes with the Avago ADNS s3988 sensor, which is also very highly rated. The Avago ADNS s3988 of the DeathAdder Chroma is superior performance-wise. However, I would have to recommend the Zowie FK1. Many people complain that the ergonomics of the DeathAdder Chroma is not comfortable and that, realistically, you will not notice a significant difference between the Avago 3310 and the Avago ADNS s3988 sensors. This is a chart comparing the ADNS-3988 sensor (Avago ADNS s3988, DeathAdder Chroma) and the PMW3310DH (Avago 3310, Zowie FK1). It essentially reaffirms what I stated above.
