GeForce GTS 450 1GB SLI Testing
While I didn’t have time to run the complete gamut of performance tests in our system configured with SLI GTS 450s, I was able to run a handful of benchmarks at 1920×1200 with two of the reference cards from NVIDIA.  Let’s take a look at the results:

The scaling percentages that NVIDIA continues to pump out are impressive.
  • Far Cry 2: 89%
  • HAWX: 94%
  • Metro 2033: 93%
  • 3DMark Vantage: 91%
How NVIDIA has been able to make such a drastic turn from the days of the 60% multi-GPU scaling is something they won’t divulge though they did say it was designed as much in the hardware as it was in the software shifts. 

Also note that in our SLI testing the pair of GTS 450s is faster than the single GTX 470 in all games except Metro 2033 due to the heavy use of tessellation and the GF100 GPU’s advantages there.  Considering you will be able to get a pair of GTS 450 cards for about $250 and that a single GTX 470 will still cost you about $280, that combination should definitely be a consideration.
