I've been browsing around and have seen a line of X1 cards for sale online and was wondering what the difference is between the X850 I have and the X1 I see available. In particular, I'm seeing X850 card w/ 256MB of GDDR3 while the X1's are going up to 512MB but of GDDR2. What is the performance difference and why the different grade of RAM? In addition, why is the X1 series of cards appearing much cheaper than the X850's I see out there?
