Looking for a new audio interface for Windows 7 64

So yeah I want a new USB audio interface.
I currently have an M-Audio Fast Track, and it has some severe issues I think with the drivers that results in random clicks and pops and horrible distortion sounds when I'm producing.
I've been looking at a few different ones that keep cropping up on these forums, NI Komplete Audio 6 and Focusrite Saffire 6 being the main ones, but with a bit of googling both of these seem to have some issues on Windows 7 64, and the Saffire apparently has issues with Intel i-series chips (I have an i5).

So my question to you is - does anyone know of a good USB audio interface around £150-£200 that works on Windows 7 64 bit, with an i5 chip, problem free?
I really do not want another repeat experience.
