Last year, I wrote about mixed CrossFire and by that I mean joining video cards like the Radeon HD 3870 and a Radeon HD 3850 together in CrossFire for a better gaming experience. At first this might seem like a silly thing to do, but for those upgrading their system on a budget it makes perfect sense. If you buy a Radeon HD 5870 for example, and six months to a year down the road a friend of yours is selling his prized Radeon HD 5850 to pay off some bills for an insanely low price, you can buy it and CrossFire them together for better gaming performance.
