yeah .. i had a bad experience with the BFG FX 5500...i don't recommend any of the FX 5 series...they're a complete failure i'd say...i'd go with the 9600xt..are you on a budget? i'm assuming this card ain't for you...but yeah i'm all in with the 9600xt IMO
what are you benching with the 76oogs on sli?
Check this out. The comparison is between an FX5600 Ultra and a 9600XT and the latter aces the NVIDIA card at everything. So it's a no-brainer that the 9600XT would destroy an FX5500.
