Can someone explain to me the differences between brands like gigabyte, MSI, xfx and others? What makes one brand of for example gtx 770 is 100 dollar more than another brand of 770. I'm asking this because I'm trying to sli 2x 4gb 770 and the cheapest I found are these http://pcpartpicker.com/part/pny-video-card-vcggtx7704xpboc.
This is my first time seeming a pny GPU, even though the reviews are like 5\5, is there something wrong with these card that make them so cheap?
 
for nvidia i would prefer evga. other than that the differences are in the coolers and how quiet they are and how well they cool compared to the reference nvidia design. the different models you see from the same brand are binned chips that generally overclock better. but any brand will serve you well. these are all big companies that stand behind their products. warranty length might be something that you may want to pay attention to if it gives you peace of mind. evga has the best warranty and customer service in the business. but msi, gigabyte and asus are the other three huge companies that offer somewhat comparable warranty and customer service.
