[Wine] Speeding up wine emulation- benchmarking?

[G4BBH at Winlink.org]

I will have to replace the ageing Pentium 3 at 1 Ghz system here fairly soon.  I am looking at dual core processors amongst other things. Firstly can someone recommend a (windows) benchmarking program that I can run under wine.  Also 
can they give me some idea of the results to expect if I run alternative processors and how much dual core affects wine.
Thanks
