I just got this reply back from EVGA via email (see entire message below). Is this guy correct, or is he just promoting the higher cost product? From what I have heard, the 7800GS CO is the exact same card as the 7800GS CO SUPERCLOCK, except it is not overclocked which i could do the same thing my self and they would be identical. He is saying otherwise? Any opinions or advice? Thanks!!!
"Michael,
I cannot answer specific overclocking questions about the differences between the 1.6 and 1.4ns memory due to the fact that we do not officially support overclocking in that capacity. I can only tell you that the Superclocked cards have passed rigorous testing to be stable at the rates they're sold at. The N505 is not guaranteed to run at the speeds of the N509, and we will not support it if it does not as it is meant to run at its stock speeds; with overclocking, your mileage may vary. All of these cards support the CineFX and Intellisample 4.0 capabilities, which is part of what makes the 7 series cards better all around than the previous technologies".

One more quick question:
Between these three models I am seeing and hearing these differences from forum groups:
7800 GS CO Superclock (EGVA fan N509) 1.6ns memory , CineFX 4.0 engine, Intellisample 4.0
78800 GS CO Superclock (reference fan N508)
7800 GS CO (Evga fan N506) 1.6ns memory, CineFX 3.0 engine, Intellisample 3.0
7800 GS (Reference fan N505) 1.4ns memory, CineFX 4.0 engine, Intellisample 4.0
Is the 1.4ns memory better? I am hearing the lower this number the better overclocking potential it has? If so why is the Superclock card at 1.6ns memory? And why would the (N505) with the 1.4ns memory be the cheapest card?
Also, what is the difference between the 3.0 and 4.0 versions of the CineFX and Intelisample?
Which cards have the better copper heatsink?
Which card is the overall best if I want to overclock the card myself?
Thanks Chris.
