In this article we're going to check gaming performance of Intels high-end LGA 1155 Ivy Bridge and Sandy Bridge CPUs when they're being supported by a Radeon HD 7970 graphics card from XFX. We're curious if there will be a measurable performance gap between these two CPUs regarding modern games or if the 100 MHz more clock speed and the architecutral changes don't even have an influence on gaming performance.
