Hosting Queries and other dohs!

I'm new but know the ropes and am in the middle of picking anew dedicated server for
a new site.
Query1: anyone using volumedrive.com, server4you.com,serverloft.com they all offer
something too good to be true (enter spammer with bad feedback on these while plugging his affiliate host....!)
Query2: This new site's FHG get 15-30000 visitors per day, what kind of machine will do;
eg am looking at dedicated host with AMD Opteron3280(8core)/Intel Xeon 3450 (quad)
both at between 8-16 RAM, 2 HDDS blahblah
Would any of these be good for this kind of traffic, who mostly are bouncers and sell them anyway?

Just giving a shot guys (am in abit of a dillema and must decide quick)
cheers
