Not all GPU's are made equal

My mate Drew sent me a version of the model I've been using with much nicer UV's. So all the pixels are aligned and have a consistent uv density. Which is awesome, But it means I needed to compute all new lighting textures and I didn't want to wait two days like last time. So I installed windows on my Linux box and got it rendering. And I also got my laptop rendering too. But you can see from this data it wasn't really worth it.

Computer	GPU	Gflops	Light 268435456 pixels
Build(Linux Box)	6600 GT	47	~386 hours
Laptop	GT 620M	269	~64 hours
MainPC	GTX 460	907	~22 hours

Any way here is what it looks like.

Hard to see from this image but trust me it looks a lot nicer. Once I fix up the bilinear filtering I'll post another video and you can see for your self.

But I really want to try a 32k * 32K texture next. Which would take about 8 days! So looks like I have some optimizing to do. Unless anyone has a render farm they are not using?
