hallo746: I've had a lok for some ATI 5670's ones that are showing up are Spphire and Asus is there any diffrence?
Not much. AMD/ATI makes the chips and a reference video card, and then lots of other companies, including Sapphire, Asus and a dozen others make their own cards that are basically identical except for a different fan, and occasionally somebody puts a bit more or less memory on it, or plays with clock settings a bit.
When I bought my 3850, I went for Peak, a brand I'd never heard of. But it was a lot cheaper than others, and a bit of research showed that its only real problem was a crappy cooler. A pretty serious problem for most people, I admit, but I didn't care because I was going to replace that cooler anyway. My 3850 now has had passive cooling for over 3 years now, and I've never had any problem with it. Best purchase ever. But I admit that's because I did my research and knew what I needed. For most people, it's probably better to not skimp on money and go for the quality brand.
