Part of the reason why AGP systems are still abundant lies in the lack of urgency to mass-upgrade for those who have already invested in very decent AGP systems. While another relatively lesser-discussed reason lies in the fact that newer CPUs haven't really improved gaming performance significantly since the late days of AGP's heyday. Remember that we've mostly progressed into multi-core processors these days? Well, if you've been keeping tabs on our reviews, you would realize that dual-core and quad-core processors offer little gaming advantage so far. That brings us to the graphics card quotient that really makes or breaks a game's playability (as long as the system is decked with at least a decent amount of main memory).
