I'm getting a new comp and since the x1900xt had been discontinued I had the choice of a 7950gt or the x1950xtx for $140 aud extra. So naturally I went for the x1950xtx because the 7950 would be a downgrade from the x1900xt. So I'm just wondering is there anything that I should know in order to get the most out of this card w/o overclocking like utilities etc..?
