Then when they decide to go big with 1920x1200 or 1920x1080, adding a second GTX 550 Ti in SLI should give them high-end performance that lets them play anything at HD resolutions.

floating point performance How fast the gpu can crunch numbers

GeForce GTX 550 Ti
691.2 GFLOPS
GeForce GTX 280
622.1 GFLOPS
While double precision is not infinitely precise for floating point numbers it is as good as what is available in today's CPUs.
GeForce GTX 280 | by techPowerUp! (Jun, 2008)

shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading

To accomplish this task, the GTX 550 Ti is based on new 40 nm GF116 silicon, which packs 192 shader cores, and a 192-bit GDDR5 interface.
