GeForce GTX 550 Ti vs GTS 250

older Released March, 2011

Nvidia GeForce GTX 550 Ti

900 MHz
1 GB GDDR5

It makes for a good bargain, but even with overclocked speeds, things don't change much for the GTX 550 Ti in its competitive.

But Nvidia’s board partners deviated from that configuration unanimously, going to market mostly with two-or three-fan coolers, which I frankly don’t care for as much.

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.
