In our second review of an XFX video card, we have the Radeon HD 4890 1GB. As you might recall, we reviewed our first ATI based XFX video card in the Radeon HD 4850 1GB and found it to be a great option for gaming on a budget without making sacrifices in image quality. Today we are looking at the big dog of the 4000 series cards from ATI, the 4890.Unlike the Radeon HD 4850 and 4870, the 4890 comes equipped with a minimum 1GB of memory with some add-in board partners upping the ante to 2GB. On our card today, XFX chose to stick with the reference design Radeon HD 4890, which means that our card has 1GB. Being that it is a reference design, the GPU is clocked at 850MHz, while the memory is clocked at 975MHz. These numbers are nothing to scoff at; the ATI Radeon HD 4890 video card still has plenty of gaming performance for those looking to spend less than $200!
