Compared to the GIGABYTE HD 5830 the card clearly stands out in some areas and not in others. The extra price might be an issue for some, but the high quality cooler of the MSI card could be a clear standout reason to spend the extra money.
The other ability with the card while not shown here is the ability to adjust the voltage of the core. This would yield even higher performance gains and while not available on the sample we got which was part of an early revision, we may end up with another one in the near future to look at which has the ability.
The voltage adjustment for some is priceless and means that the value of the product is increased even more. You can actually see over at Newegg.com that the card is listed with a note saying "OverVoltage Support by using latest AfterBurner 1.5.1".
The HD 5830 I personally feel is a good valued product and when you throw in the fact that it overclocks well when using a nice cooler like the Twin FrozrII one from MSI, its value is increased even more.
If you're looking for something that stands out from the pack when it comes to the HD 5830, this is one worth looking at; especially if you're interested in looking more into AfterBurner and its voltage adjustment ability.
