I am looking to build a gaming computer for about $700 and so I took ideas from the $500 gaming rig mentioned on this site and the $800 gaming rig from ExtremeTech. I would be very grateful if I could get the advice of the people on this forum. I plan to overclock the CPU to somewhere around 3ghz (is this wise?). I currently play Team Fortress 2 and DoD:S but would like something that leaves the possibility to play future game releases at a decent quality (Fallout 3 comes to mind).
Alright well this is what I have now (thanks to doubletake33 and modode). I have one question about the overclocking the processor. Say I were to over clock it to 3.0ghz, how much of an effect would this have on the lifespan of the processor?
No one really knows the answer to your overclock question for sure. Traditional wisdom is that heat is the enemy of CPU lifespan, and the nice thing about the Wolfdale CPU's and their 45nm technology is how cool they run, even when oc'd. My guess would be with a modest oc to 3.0 and the aftermarket CPU cooler you've selected, the lifespan of the CPU probably would not be significantly affected at all.
I really like your build at this point in terms of the performance/dollar.
