Hi everyone, I am wondering what will happen, regarding to performance increase or decrease, if I add this graphics card http:// to my current card, which is this one.. http://. I know it will bring the specs of my higher card down to it that of the lower, but my question is, would the sli of essentially the lower version be better performance than that of the higher by itself? The ONLY reason im considering doing this is because the price of the lesser card that I can obtain from someone locally is basically just a few bucks, so would be worth it if i saw much performance gain.... pls help or point me in the direction of a case where someone did something similar and had benchmarks! thanks!
