Alright, ran tests with AIBB
Not too sure what some of these tests indicate, so just reproducing the numbers here
For comparison, I included the numbers given for an A4000 in parenthesis, which the system assumes is the 040, with 4 megs fast RAM added.
EDIT: These numbers are all in comparison to a stock A600.
Linetest - 2.53 (1.87)
Savage test - 13.51 (a4000 14.x1)
Fmath test - 11.67 (16.18)
Fmatrix test - 13.64 (11.45)
Beachball - 16.07 (18.69)
InstTest 14.24 (10.05)
Flops - 13.3 (16.92)
Trantest - 13.89 (15.18)
Ftrace - 13.61 (15.58)
Cplxtest - 12.94 (15.28)
Ellipsetest - 7.64 (5.46)
Matrix - 15.18 (12.17)
Imath - 15.7 (17.15)
Memtest 15 (3.48)
TGtest 4.44 (3.81)
Emutest 13.28 (16.72)
Writepixel 8.72 (15.33)
Sieve 15.6 (10.54)
Dhrystone 14.53 (19.2)
Sort 16.21 (19.52)
Looks like this card is pretty close to an A4000 in several areas, overtaking it in some. Not shabby for a little 1200

My conclusion would probably be, if you already got an 040 or 060 card, you may not benefit from this. If you need an accelerator, get this for sure. Especially at the price given.
Had some trouble with sysinfo, but I'll keep messing with it
