Oh ATI, that's why I have never heard of Sapphire, I thought ATI died in the 80s, people still use them?
I only use ASUS boards, Gigabyte if I really have to..
ATI is the company that DEVELOPES the graphics card, other company such as Power Color, Sapphire, Asus, BFG are the one who MANUFACTURES the card and sell them for retail. ATI is on par with Nvidia, so don't be a biased.
PC components really come down to personal preference,
I have been using Asus/Nvidia cards for over 15 years and I have never had one problem, cant argue with statistics
Intel is more power, but cost more. AMD is less power but less cost, AMD if you are trying to build a budget PC, Intel is when you want a powerhouse. As I said, ATI and Nvidia are on par, you cannot compare totally different series of cards if you're gonna compare statistics.
