How is this eVGA 7800GTX (P/N 256-P2-N527-AX) for overclock?

Here is the link for the same card evga 7800gtx
Just bought from an AT mate seller for $345 shipped. This is to replace the 6800 (vanilla) and to be used in my AMD gaming rig. How well is this beast known for its overclock ability is what I wanted to know.

Its already overclocked by eVGA to 470. Stock 7800GTXs have a 430 core speed. You can probably get this particular card up to 490 without a problem but to go beyond 490 you'll need some really good cooling. Top end speed I have heard of 7800GTXs getting to is 530 but thats with some serious cooling I imagine. Also remember when overclocking these cards they drink more power and heat things up inside the case.

Not to mention eVga is the sh*te.

Edit: Haha, just in case that was unclear, that was a compliment not an insult :|
