Ok calm down, websites do and will continue to put wrong, false info about products.
I agree there is a 512mb 6600gt, the fact is though this edition is purely marketing not performance orientated. There is no benefit of 512mb over 256mb on what is now a budget card.
That edition is aimed at people who like big numbers, most people do not know what core or card version numbers mean, what most people know is that more ram is better right, well in this case not really.

Now this card is intresting and in my opinon something has been put in wrong. It says its 16 pipeline well if its a 6600 it cant be in can only have 8.
If it had 16 it would be a 6800gt, why would any company sell a higher card under a lower card identity they just would not do that.
It has an OC designation yet nothing is overclocked its all stock.
The company website has no mention of it.
Right then as for the first card:http://www.microcenter.com/byos/byos_single_product_results.phtml?prod..._id=023
Have you noticed its heavily under clocked, it has it listed as a 300mhz core speed when the stock speed should be 500mhz. Its bandwith is way under the stock 6600gt.
So the website either has some serious marketing errors or there are some serious attempts to con people.
Like the others said the 6800gs is a much better card than the 6600gt the 512mb means nothing in real life, and if you bought the underclocked one then you would have been seriously ripped-off.
