A Boxxing match or a match made in heaven?

My new machine should be here tomorrow morning (can't wait - Core i7EE @ 4.15GHz, Quadro FX 1800).  It will have Win 7 installed, and we are still on SW2009sp3.0 with EPDM of the same version.

I realize that this is not a SW supported config.  Am I going to have problems, either with SW or EPDM Client?

Should I try it or just format and go with WinXP 64 bit?

Any results from a similar setup?

Thanks in advance,

Chad
