>> Palit Geforce 280 GTX Review
Among the highest performing video cards currently available is the GTX 280, as it is currently the most powerful single card on the market. Michael Lynch takes this bad boy for a spin to show you how well this video card actually performs by itself and in SLI. Palit was gracious enough to send us two of their top-notch video cards to let us test out the true power behind the GTX 280. Now only one question stands in our mind. Can two GTX 280s in SLI run Crysis with maxed-out settings? Ohh Boy, we will see!
