Your PC? It sucks, it doesn't have enough cores. Sure, you could get a new multi-core processor like a Phenom or Core 2 Quad, adding like 2 or 3 cores to your rig. Or! You could get a new graphics card instead and get over one hundred extra cores. And more cores = more better, right?
Actually, even though Nvidia's argument seems slightly retarded and self-serving, it has a bit of merit—as you go up in CPU price ranges, the price to performance ratio drops pretty steadily. And if you're running Windows Vista, you actually need a solid graphics card to run it without any hitches, even if you're not gaming. So instead of plowing an extra $100 into a slightly faster processor that'll net you minimal performance gains, you'd get more out of it investing in a better graphics card. [Nvidia via Pop Sci]
