What is the lowest price on a good gaming laptop?

I'm looking for something really good with these minimal specifications: Intel core 2 duo at 2.4, or intel core 2 quad at 2.0, at least 4gb of ram (preferably ddr3 and fast), AT LEAST an NVIDIA g9800, i don't care about the hard drive, and I'd prefer it have a 17 inch screen at 16:9 ratio, but id be happy with a 15 inch or a different ration. So what is the cheapest laptop with these specifications?
