Hi all, I'm currently on the bench with deciding between the W5590 or X5677. There is a seller that I've found that can sell a pair of w5590's for £84. I can't seem to see anywhere (Apart from China) that has the 5677's at a decent price. Would it really matter that much if I just went for the 5590's over the 5677's? I spend a lot of time on MS Flight Simulator X which only really takes in clock speed and a single core. I currently have a dual 2.4ghz machine. Who ever has had both, what one would you recommend and why? Would it be worth waiting for a decent supplier for the 5677's? Pro's and cons of deciding with the 5590 over the 5677?
