I understand about the budget  :-(
My experience with RAID 0 (s/w) on RHEL Enterprise Server with only CVS 
and Oracle and 10 developers I see serios processor load from RAID 
support. :-(
On the same configuration (with 1G of ram, 2XPentium 1GHz) exp command 
make load on 50% with serios amount of i/o operations.
BTW: If you are buy already controller try it on other machine with 
Knoppix for example to make sure is not recognizable as other kind of RAID
