? for the experts regarding the HP Pavilion dv7t Quad Edition (with the new Sandy Bridge CPU's)

Question

Hello,
This is a question for the experts.
The HP Pavilion dv7t Quad Edition has the following GPU:
1GB ATI Mobility Radeon(TM) HD 6570 graphics
Is this GPU GDDR5 or DDR3 in this laptop?  I know someone that purchased one from a MicroCenter and it shows GDDR5 on the packaging (http://www.flickr.com/photos/bravoexo/5298674802/) and in GPU-Z, but I called HP support and they said it was DDR3 (although, HP support told me that GDDR5 didn't exist and that DDR3 in GPU's were the most advanced to this date).
Please let me know ASAP, as this is a main factor in me purchasing this or not.  I can find other DDR3 gaming laptops out there for less, but if this really IS GDDR5, then I'm sold.

Thank you both for your questions and answers, I was wondering the exact same thing. I'm ashamed to admit I already began the process of perchasing this computer prior to having all detailed specifications made available.
I'm upgrading from a 13.3 inch HP laptop called the dv3510nr. It was never intended for enthuiast gaming, but it has exceeded the sum of its parts. It does have dedicated graphics, backlit keyboard, other novelties that make it the best computer I've personally ever owned.
Few people can say they've managed to run Fallout 3 or Supreme Commander at maximum detail on a 9300M GS. It has 512 MB of DDR2 memory, 4 GB system memory and a 25W P7350 Core 2 Duo processor (2.0 GHz)
Its served me well but mobility is no longer a priority. I waited until Sandy Bridge was announced and took the plunge immediately. 6 GB of DDR3 RAM, a 6570 with 1 GB, 1600 x 900 display AND best of all:
-The i7-2720 quad core processor, (2.2 GHz, up to 3.3 GHz with Turbo Boost)
--for a total price of just over $1,000 after taxes. With 2 year warranty standard.
For brand new, bleeding edge technology not yet even widely available, at such a large upgrade margin at an absurdly low price; I didn't need to know anything else.
So imagine my excitement when I learned this 6570 was in fact based on the old 5770 (the lowest available card with GDDR5 support), not the 5650; and could contain a 1 full GB of the fastest memory technology on the market, GDDR5.
That would mean virtually no bottlenecks in my system as a whole; I don't have an SSD but truth is, I don't like them anyway. They don't last very long with 'wear leveling', cost too much and only impact synthetic benchmarks.
My new DV7 can't get here fast enough.
