I'll tell you why ur friend thinks 753 is better.
the 64bit 754socket runs on higher Hz. like 939 3GHz runs on 1.8GHz.. while the 753 runs at 2+ or something.
but look at the bw system:
HyperTransport bandwidth: up to 6.4 GB/s (753)
HyperTransport: up to 8.0 GB/s (939)
Memory bandwidth: up to 3.2 GB/s (753)
Memory bandwidth: up to 6.4 GB/s (939)
Total: up to 9.6 GB/s (753)
Total: up to 14.4 GB/s (939)
The numbers speaks for them selves..
