I've sh**ty internet connection here so I can't confirm (with i.e. searching the article(s) on inet). So fast, man! ~2.1 KBps. Yummy. With the advantages of can't-googling.
Oh, And if you want an NVidia card, wanna change with me? I've 8600GT, heheh.
edit: finnally, can googling. I've used `nvidia+offer+amd+physx` and there's several result. U can read it by yourself.
