my build wasnt useless, it just obviously wasnt the best of the bunchand tbh ssd on that build budget seems pointless, best off with a nice big hdd and spending more on gpu..
i know the 950 is new and cost more, but i didnt think it be any better than the 750ti?
edit: usb2 not that bad really, but other than this enclosure i have nothing nor see anything useful to me to use usb3 until everything goes usb3.
A 950 is faster than a 750ti (i have had both)

And that previous link I gave also shows this.
As for USB3.0, even just putting a large file (film/Game download/anything) on to a USB3.0 device using USB3.0 is significantly quicker than 2.0.
Again I've been there and done that and got the Tshirt.
