The discussion centers around the inadequacy of quad SLI with four Nvidia 580 graphics cards for high-performance tasks. Despite the 580s being among the best cards available, the original poster seeks suggestions for upgrades, indicating that their current setup is no longer sufficient for their needs. Other participants express skepticism about the necessity for an upgrade, noting that even less powerful cards can handle demanding games like Skyrim at max settings. The conversation shifts to potential professional applications, such as CAD work, which may require more specialized graphics solutions. Recommendations for alternatives include high-end options like the Quadro 6000 and Firepro 9800 for those needing enhanced performance beyond gaming capabilities. The discussion also touches on the viability of developing games that cannot run on existing high-end hardware, questioning the business sense behind such decisions.
