Realview performance requirement

Hi, I am looking into buying a new graphics card.
Based on previous experience of premature hardware deaths I wouldrather not spend a whole lot of money especially given theridiculous cost of CAD cards vs the same hardware presented as agaming card
It looks like either a FX570 or a FX1700 would be a candidates forpurchase.
My question relates to the graphics power required for Realview inSW2009.
The various benchmarks I can find seem to relate to performance inmore traditional CAD or DCC senses I think.
That is they are concerned with wireframes or shaded views or say,gaming type textures. Further the usual ones like Specview used bytesters often relate to older SW versions.
Can someone please describe to me from their seat of the pantsexperience of realview if a FX570 has enough grunt to run fullRealview with an assy of say 100 parts.
I had an old FX4000 for SW 2005 that probably runs about as fast asa FX570 if the general specs are to be believed but I think myselfthis will be a bit 'marginal' in reality for SW2009.
It would be great if a SW employee who tests these cards forcertification or who is a member of the Realview development teamcould provide some recommendations or guidelines.
How about some sort of in house test or rating? or even a testincorporated into the program..
