When Palit said they were sending over their GT 220, I didn't think much of it. When I received the video card though and found out it was a Sonic Edition model, I wondered why they would even bother putting the model in their lineup.
With that said though, once we fired the video card up, and looking at the numbers compared to the Galaxy version, we were surprised at the performance increase the model offered. While the extra MHz looked good in GPU-Z, we weren't sure if it would translate over to our benchmarks - fortunately we're glad to say it did.
If you're happy to spend a few more dollars over a stock model then the Sonic version could be worth it, depending if you're willing to spend the money or think that a gain of around 10% is worth it.
Really, apart from the performance improvements, there isn't a whole lot more to look at, the bundle is on the light side, the cooler isn't exactly fancy and while it causes the Palit version of the GT 220 to run slightly warmer than the Galaxy one we looked at, it manages to be quieter, which for most people is going to be noticeable and appreciated.
