However, the mere fact that there are a lot of CPU types in the today?s market, even within the same price group, can be quite confusing for the PC users. While it is not that hard to decided between the Athlon 64 and Pentium 4 processors offered at the same price point, the dual-core solutions may appear a stumbling stone. Some time ago we could simply mark them as ?not for gamers? and we could be absolutely right about it. Their working frequencies are lower than those of their single-core fellows, and the actual advantages of having a second core haven?t been used by the gaming applications at all. Now the situation has changed a lot. Graphics processor developers released new driver versions that can support multi-threading, and game developers began to modify their engines so that they could take good advantage of dual-core architectures. As we see, new shooters based on gaming engines from id Software can already use the power of two processor cores. Since these gaming engines are among the most popular nowadays, Quake 4 and call of Duty 2 may very soon become far not the only ones using dual-core. Moreover, it wouldn?t be surprising at all if some other gaming engines also acquire dual-core support: progress keeps going forward.
