Will the following differ much with nginx for an upstream webserver (running PHP and fastcgi) and accessing files over NFS? Quad-core Xeon 3220, 2.4ghz, 2x4MB vs. Dual-core Xeon 3060, 2.4ghz, 1x4MB Both with 4GB RAM, gigabit ethernet, SATA2 7200RPM disk. It should work very well either way, right? I don't think I'm using the quad cores that much...
