High Server Load

|Here's the specs of the server:
AMD Opteron 248 DualCore DualProc Sata/Sas [2Proc]
This is just the web server. Load gets really high randomly causing the site to run very slow and times out. We get around 80-90k uniques per day.
Do I need to upgrade hardware or is it the server configuration that needs to be optimized?

|48 load average but CPU 99% idle, and no swap file use suggests the problem is probably that your system is I/O bound - something is doing too much disk I/O for your hardware to cope. You already have a 2.2Gb disk cache so more memory may or may not help.
You need to find out what and then decided if a better storage system is required, or better code. Running iostat will help confirm that this is the issue. Mind you, normally you would see more io wait time for the CPU, so it may be something else.
