I'm using the 6/03 version of FX with WB5 and it's running great. When I started with this version I was "glad all over" it cleared all the problems up that I was having with the earlier versions and uses almost no resources. Unlike the previous version that put my AMD 3400+ /2gigs Corsair/ and 6800 GT to a test, worked but a resource hog and really glitchie.
