ATI Rant Time

ATI... Sure does suck... Sure. DDR5 technology. Does nothing to perfect gaming performance. Their 'high-end' 4000-Series GPUs get lower frames compared to Nvidia's GTX 200 Series GPUs.

Sure the prices are higher in Nvidia's case but that's what you need to sacrifice for high-end gaming. Not 'high-end gaming'. HIGH-END gaming.

ATI's shader core quantity also reflects their quality. Too many cores for example in ATI's HD4770 (640 cores) have to compete with Nvidia's GeForce 9800GTX+ lower core number (126 cores) to achieve the same amount of performance.

These abundance of processor cores from ATI also churns out an enormous energy to process the same amount of data a lower amount of processor cores from Nvidia. Therefore, your electricity bills will skyrocket with ATI compared to Nvidia.
