I have a Asus P4B266 mobo with a P4 1.7 willy, 512 corsair DDR266 and a GeForce Ti4400. I am thinking about dropping in a 2.4 P4 with the 400 bus. I know everyone is moving to the 533 bus, but at the moment I don't have the bucks to replace the cpu, mobo and ram. The performance gain with the 533 bus seems somewhat minimal at the 2.4 level according to the benchmarks on Tom's site. My question is whether I will see a good performance boost with the 2.4/400 vs. the 1.7 willy? The 2.4 can be had for $195 online. The alternative is to wait another 6 or 7 months and build a whole new system then. Thanks for any thoughts.
