He could also spend that $150 on upgrading his graphics card, CPU, or RAM and get a much larger performance boost. $150 can get you from a 7600GT to an 8800GTS, you can add 4 gigs of DDR2-800, or upgrade from say a 3 GHz P4 to an E6600.
(You'd actually be best off combining them, maybe getting an 8600GTS and a gig or 2 of RAM)
Physics cards are gonna become obsolete. High end graphics cards and CPUs have more than enough power to also do physics work.
