So I need a video card for my gaming PC build and I've noticed that the GTX 950 1.20 ghz is higher in price than a 1.17 ghz or a 1.03 ghz or a 1.15 ghz...you get my point. Whats so special about the extra ghz in a video card and Will the extra ghz be beneficial for performance when Gaming?
I'm still learning what all these little details mean so excuse me.
Thanks :)

Ghz on a GPU (or CPU for that matter) is how many clock cycles the card can complete per second. So in terms of raw processing power, a 1.1Ghz GPU will be 10% faster than a 1Ghz GPU. There are other factors such as memory bandwidth which sometimes come into play, but generally speaking a card's performance scales with clock speed (=frequency = Ghz).

As Hydroshot says you can overclock a card yourself (raise the clock speed), which usually works (there are no guarantees). But if you don't want that complexity, you may as well get the card with the best price/performance ratio. With higher end cards, the coolers start to matter because the cards produce a lot of heat and keeping them cool can be noisy, but 950s are pretty low power...

basically different brand makers will have different clocks and prices while still being the exact same card. its more of a marketing trick to get people to buy the highest clocked card for the most money. there may be 1 to 2 % performance difference in higher or lower clocked cards
