I will have multiple long HDMI runs - should I buy the better cable?

I am going to run HDMI from my pc to all 4 TVs in my house. I could use a 30' cable on one of them but I'll probably just order 4 of the same 50' cables since that is what is needed for the other 3 TVs. I have a good video card and I I certainly dont want to spend $1200 more to have 4 of them and have them connected all the time. I'll buy a hdmi switch or possibly a splitter (I will never want to display something from my pc on more than 1 TV at a time). How important is the type of cable I chose with this configuration?

Cable possibilities:
28AWG and 26AWG were only in short lengths. 24AWG high speed skipped from 25' to 75'. That leaves me with the options below:

p.s. what would happen if I bought cheap video cards with hdmi out of them for the other 3 TVs and connected it that way?


THANKS A LOT!
