These are a fantastic bargain of you're using them as longer runs than the 4-6ft cables included with monitors or standard ones you get at best buy or frys/micro center, whatever. The 9ft length are fantastic for me, and the price is extremely reasonable. These pushed an mg279q 144hz 1440 monitor at full 144hz off a 1080ti no problem, and push an overclocked alienware AW3418DW 34inch ultrawide at 1440 at 120hz no problem either. These cables aren't cheap, they're made well, and I'd put them up against any middle of the road cable any day. They are very cheap too.Great cable, totally worth it, don't worry about buying these. They'll be just fine.
