If you're a regular reader, and if not why not, you'll have been awaiting today's review. After dipping our metaphorical toe in the triple-screen water with the HIS HD6990, today we're back with a nVidia offering in the form of the Zotac GTX590. Of course we could just review a single card, but as Zotac kindly offered to lend us two so we could run in SLI we'll be testing in both forms today.
