Introduction

Today, AMD launched its Radeon HD 7700 series to solidify its competitiveness in the sub-$200 graphics card market segment. The launch consists of the Radeon HD 7770 and Radeon HD 7750, both capable of 2-way CrossFire. While we don't expect anyone to buy two HD 7700 series in one go, since there could (we're figuring that out in this review) be better single graphics card options in higher price points, CrossFire capability allows users incremental upgrades.

People can get one HD 7700 series graphics card now, and add on a second card later, as their performance needs go up. A CrossFire upgrade could also let people game on higher resolutions than what a single HD 7700 series graphics card is meant for, so really, the 'incremental upgrade' argument is the only sensible way we see people buying two of these cards.

What's more, AMD's architecture allows you to pair between different SKUs in a series. For example, you can pair a Radeon HD 7770 with a Radeon HD 7750, so that adds a lot of flexibility. In this review, we will measure the performance of two HD 7770 in CrossFire, and two HD 7750 in CrossFire.
