Go for it... I doubt it'll give you any issues, because I had it on my ancient 1.86 GHz Celeron M w/ 1GB RAM, and it was just a tiny bit slower than XP. Dual-core Pentium and 4GB RAM will handle it just fine. And, as it was mentioned before, you'll be able to use DX11 (though I don't know if 4670 supports it).
