Is it anyone that can give me answer if this computer will make Poser works faster and more stabile??

I want to buy a new computer, because the computer I have now renders VERY slowly and Poser shut down all the time.. I get crazy with all the problems..

My computer I have now is:

AMD Athlon 64 X2 Dual processor
2 GB RAM
Videocard: GEForce 7300 FS

THE NEW COMPUTER HAVE:

Core Intel® Core™2 Quad  Q6600 processor 2.4GHz,
4GB RAM, 2x2GB DDR 667MHz
Videocard: PointOfView GeForce 8600GTS 256MB

Will this computer be better for working with Poser 6 and 7????
