Hi

I am wondering what is the best graphics card for value for FSX and other simulation software. I know FSX is a CPU hungry game but it still needs a graphics card for enhancement of textures etc. At the moment I am looking at the Sapphire HD 7770 GHZ edition with 1gb of GDDR5 ram. Is this a good enough card or is there something better? I cannot afford anything more than this but i am happy to go lower if I can still get a quality graphics card. I have no preference of manufacturer

Thanks for the help
