this card replace EVGA GTX 285 which have 240 CUDA core -- gtx 560 ti with 448 CUDA core ; I definitely notice a difference with my 3d programs-rendering time be quite a bit faster . card require 2 6-pin power connector ; the instruction refer to as '' +12 volt Rail Amp '' . the card be easy to install ; however , I be unable to load driver from the website so I end up have to use the CD driver as well as other reviewer . I trust evga as my gtx 285 be still work ; I replace it because I want to have the ability to connect my tv and 2 monitor to the card . resolution and refresh rate be very close in comparison to the 570 which I almost buy , however , the selling point for this particular card be the output -- that be it have a Display-Port and a regular size hdmus port rather than the mini hdmus port -lrb- find on the gtx 570 - and other higher end card of this type -rrb- as well as the additional CUDA Cores .
