>> GIGABYTE Radeon HD 5830 1GB Video Card Review
Love it or hate it, the HD 5830 is here to stay and some may feel that it's a better option over something like a HD 5770 because ATI tend to focus on adding performance to their higher end models. With the HD 5830 falling in the HD 5800 series range, one would hope that it may see more of a performance bump than models in the HD 5700 series.
The models are beginning to come in thick and fast and we've got a couple here from a few different companies. The first one we'll be looking at today comes from GIGABYTE and carries with it quite a mean looking cooler.
