yogy :
that i didn't think about ,would dell be so unfaire ,maybe if he dose a bios update
It's not a matter of fairness so much as it is liability, if DeLL were to give users the options to overclock then they must include some notice of voiding the product warranty, since overclocking is essentially running components over specified limits, and therefore inherently more stressful on the components. A BIOS update for that motherboard will never include settings for overclocking. The only thing DeLL might do is offer some software that would basically enable turbo boost always on or a "game mode" setting that would do minor overclocking.
See the
best answer in this article for information on setting turbo boost to always on, more than likely you will have to go into BIOS and look for a setting, and if no such setting can be found then go into advanced power management and set your processor minimum state to 100% to trick it into thinking it is under load and enabling turbo boost.
The graphics those guys are showing is pretty good, the last flight sim I used was
Microsoft Flight Simulator 2004: A Century of Flight and on older hardware so as to what your hardware should be able to do I cannot say but you do have pretty good hardware. The trick might be using mods and turning up detail in certain areas and down in others. According to
this a higher CPU clock speed is more beneficial than more processing cores, meaning the Core i7 would be less useful than getting a processor with a higher GHz rating.
Hope that helps.
