another which monitor Q....AW2518HF or XL2720

[gc4170]

I cant decide which one to get, I can get the alienware direct from dell with a 10% discount that takes it down to less than the one on the rainforest site. But I know a lot of pro players stick with Benq. Its a difficult decision. I have a 1080ti so should be able to get higher than 144Hz at 1080P, game dependant. thanks a lot - G
