Here's the way Nvidia cards work. Nvidia makes the GPU, or the Graphics Processing Unit. They sell the GPU, (which really is only a chip of silicon) to a company like gigabyte, MSI, Asus or whoever else you've seen. Those companies put the GPU onto a PCB (Printed Circuit Board) with the ram and all the other componentry needed. Lastly, they'll but some kind of cooling solution onto the card as well. This, to me, is where most of the choice comes in. I want a cooler that looks sexy but also does the job. I've found that MSI's twin Frozr works really well and looks great. Another thing you should consider is what the factory clock is on the card. MSI's cards ship with a program called the gaming app. That allows you to make an OSD (on screen display) with all sorts of information but also has three different settings for the clock rate: OC, Gaming, and Silent. OC makes the card run faster but the fans spin faster and make more sound. MSI has OC series cards which feature a yellow trim, and those come with a higher factory overclock. However, to avoid breaking the bank, I'd strongly recommend an MSI gaming series 980 ti. The last great thing about this card is that the fans only spin up when needed.
