Assuming you're coding in assembler using SSE* instructions, you can get a sustained throughput of about 1 FLOP / clock cycle. Since you're not really doing that, I'd call the 3GHz P4 about 0.5 to 1.0 GFLOP. YMMV. Widely ;) On the netburst microarchitecture used in the P4 it's really hard to get good floating point performance because of the very deep pipeline, scarcity of registers, and so-so FPU.
