You can't get the 4830, because as I previously stated, you don't have a PCI-e slot. Xlink would know that, had he looked at the specs on your board. (I wasn't just talking out my ass).... http://h10025.www1.hp.com/ewfrf/wc/documen...cname=c00387081
ahh you're right. I saw 2.9 Ghz celeron and assumed entry level system from 2006 and by that time socket 478 was dead and PCI-e was standard. I am mistaken. still though, PCI-e came out in early 2004... how the heck... eugh...
