After a rather disappointing HD 3000 series, ATI took the world by surprise with the HD 4000 generation of graphics cards. Since the launch of the HD 4000 series back in June, ATI has reclaimed its presence in the market and has been steadily eating away at Nvida's marketshare. Benchmark Reviews has had the opportunity to review several cards from the HD 4800 series lineup and today we look at one of the newest additions to the family: the Radeon HD 4830. This particular model, the EAH4830, comes to us from Asus and sports a custom cooler design and factory overclocked memory. We'll put it through its paces and find out how it compares to its two closest siblings; the HD 4670 and the HD 4850.
