My Opinion: Looks like the RV770 My very well be able to compete, and maby even destroy Nvidia in the high end sector. With the specs: up to 1000mhz clock, 2x shaders 2x TMUs, and new GDDR5 memory, I beleive that this could put up a very good fight against nvidia. Maby even waking them up to create something that could fight this monster...something better than what rumours have told us.

I'd advise to take this with a grain of salt anyway.
be that there is no crucial evidence that any of this information is true.

I am very exicted and in time for tax return too!
