is this a good brand gpu?

Id argue its the best one you can get. EVGA is a well known and great brand. They clock high and cool well with good reliability. I expected a make like Zotac when you asked if it was any good. EVGA is undeniably in the top 3.
 
hmm... you could very easily found out such info in the net. just read couple of reviews from different sites and you will get the big picture regarding all aspects. plus this will always will be education your self as well.
