It's not easy to answer the question whether volt-modification is needed to survive when gaming requirements for hardware, in particular video adapters, are getting tougher, or it is a way to squeeze more potential from a video card to get more FPS in games. The video card tested today has a performance level sufficient for all existent games, that is why it matches the latter option. For low-level solutions such modification is a way to get more FPS needed for acceptable gameplay. Volt-modification is an attempt to increase a video card's overclocking potential by changing its internal working voltages (memory, GPU, I/O circuits). But such attempt doesn't guarantee a higher performance. This procedure is identical to changing CPU and memory voltages from BIOS. One can resort to it if a given video card doesn't provide such software means.
