Hello,I have corsair 500r,asrock z87 extreme3 and i7 4770k and I want to know if there is a big difference between the sapphire r9 290 tri-x and the standard sapphire r9 290. In my country those have a 80-90 euro difference so I want to know if it's worth the money.I want hardcore gaming that will last for at least 4 years thank you.
