I just received my new leadtek 6800Nu and figured I might as well do a bit of overclocking to see how high this baby will go. Well, I'm currently at 400/900 running stable with no artifacts. I maxed out the memory settings in the program Leadtek bundled with the card for overclocking! What other program can I use to try and take the memory higher? This leadtek card has a large, heavy all copper heatsink which is doing an amazing job. Not to mention the fact that the card is really quiet. I'm currently getting 10388 3dmarks in 2003 and 79 fps at 1280x1024 in D3 with Vsync off. I definitely recommend this card for anyone looking for a new board on a budger.
