OP, your actual miner config would be a good starting point for diagnosis.

32bit is a big problem though.

Like the others said it is not your CPU.  Others with 6 GPU rigs have no problem running a low-end Sempron in them, I doubt that's issue.

I'm having issues with my 7950 also   Undecided  My intensity is at 20 though, anything less and my hash rate barely breaks 400...

I have the same card, and the same problem as you
I am also struggling getting it over 500-550

as soon as I set intensity higher as 13 I get hw errors?

I don't think it's the CPU, haven't heard of one bottlenecking a system. Hard drive speed has no bearing on performance... Post your bat / config

I've been running this for 2 months, but haven't been able to get it above 500-550 kH/s.

I'm currently putting the blame on the CPU now (Pentium 4 2.8 ghz, 4gb ram, non-SSD hard drive Smiley

i'm guessing the bottleneck lies with the CPU (only 32-bits).  is this clearly the issue?
or my settings.
