I just built my first system. I'm a bit new to alot of this stuff but learning fast after finding this site. I would have me a new dell if it werent for this site. Anyway just wondering what I should be able to get out of my system. It has a P4 2.6ghz 800mhz FSB cpu, Abit IC7 MB, 2 Sanyo 512mb PC 3200 DDR in daul channel and a geforce 5200 ultra AGP. I played around with it a bit and have it running @ 2.9g with everything running smooth. How high can I safly take it and do I need to change the stock CPU heastink and fan? Should I leave the AGP/PCI speed fixed or change that too?
