In this article we're going to check gaming performance of Intels LGA 1155 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 gaps between these two CPUs regarding modern games or if the 100 MHz and the absence of hyperthreading on the Core i5-2500K don't even have an influence on gaming performance.
