one question though. my current rig is from DS and my power supply died after 3 years. a friend of mine said it was probably due to overclocking the system. should i not overclock this time? i ended up buying a new power supply off newegg and the system is up and running again but it was a pain in the behind being without a comp for 5 days waiting for it to come in, any idea on this? thanks

ya im debating with the upgrade on the motherboard to the sabertooth. i dont know if i will ever add another video card to it, but i like to always have that option just in case.

ya i dunno what killed my old power supply. could of been alot of things. as long as overclocking is "safe", then i dont mind doing it. i dont want to shorten the lifespan of the computer. i like to keep rigs for awhile. i tend to use one for 3-4 years and then buy a new one and give the old rig to my kids.

Just that overclocking done right will not shorten the cpu's longevity.  The chips are made for it, and with proper cooling and DS doing it, really no problem.  Sometimes a call to DS is needed to tweek it a bit, but that's not the usual.
