Hello,
This month I'm gonna build my first budget G4560 PC. And I'm either buy one of these Patriot Viper 4/ Corsair Vengeance LPX/ Gskill Ripjaws V. All of them run with 2400mhz and 2x4GB, but the patriot is $6 cheaper. Which should I buy?

Im just checked out on my retailer the corsair one is 2666mhz and my Motherboard only support 2400mhz, I know that it can run at 2400mhz speed but is it okay for a long run? And is it decrease the performance if I using iGpu?
