I see he mentioned Hyperspin as a possible FE choice,just to let you know,HS works well with both trackballs & spinner controls (Ikari Warriors).
If he is going with a corei series processor,it is kind of a waste to use GameEX,especially with HS 2.0 so close to release.
Ive built a few cabs recently,so if you get stumped please feel free to ask away,you can find me here and on the HS forums,same screen name. Good luck
Also,like B2K said, a i3 2100 would be just fine for what you are doing\looking for.You can get a i3 and a msi7680 MB for under $200
