I don't get it...

So, is a Sempron 3100 (512 MB) plus a nVidia Fe5500/256MB supposed to be slower than an Athlon 2700 (512 MB) plus a nVidia TI4200/128MB?

This thing runs Quake 4 like crap!

The CPU should be fine, IMHO.

The video card is REALLY the limiting factor there though, the 5xxx series, as is mentioned below, generally performs like utter crap. Just upgrading that should give a very noticable performance boost.

And unlike the Celeron that cut all sorts of features that the main-line chips had, the Sempron is a full Athlon 64 (though early-production Semprons did have AMD64 mode disabled, all newer CPU's have it enabled) with half as much L2 cache. It's perfectly usable for gaming, and has at least as much cache as your Athlon 2700 did so that's a non-issue in terms of the upgrade.
