This VGA card receives a 8.5/10 rating from Bjorn3D for its nice mainstream performance and relatively low temperatures and quiet operation. The pricing is a tad high though.
"Recently Nvidia released their GTX550 Ti graphics cards to add to the 500 series of cards. This new card is meant to be the replacement for the GTS450 with a price point around $135, however since this is a factory overclocked card with an upgraded cooler, this particular model has a price of $154.99. These numbers are before any mail-in rebates that are offered. The base MSRP of the GTX550 is right around $20 more than that the GTS450."
