AMD. The Athlon 64FX 53 is the best processor in the world today.. and if the Pentium EE beats it by a little bit, its worth the $200 saved. And really, I think nVidia 6800 > Radeon X800.
You may even wanna go with Athlon 64 3700+ or 3800+(3700+ has 1mb L2 cache, 3800+ has the new 939-pin). They are also slightly cheaper than the FX-51.
And those WD Raptors, 2x SATA/10,000 RPM in your system would just flat-out own.
For a floppy drive.. they should be like $10 max.
$24 for 2 fans?? Complete rip unless they are like Tornados or something...
, order yourself fans to fill up every slot in the case you're getting.
Speaking of case.. wheres the case? I don't see it on your post..
