I don't know why people here are such hardcore overclock monkeys. To the OP, there are hardly any games whatsoever that are going to require more than stock settings on a modern day PC. Overclocking is a thing of the past. It comes from a time when you actually saw a drastic performance increase and it was actually worth it to overclock. It's kind of a hassle, there's always a risk involved, and as far as the payoff it's marginal on a modern PC at BEST. You don't need it, quality computers are so cheap now and games don't even come close to pushing the envelope like they did when the voodoo 3 was the big boy video card or agp was the cutting edge. Just get a cheap PC and you'll power through any game you want to play. Don't listen to the overclock fanboys, when I mentioned Sandy Bridge I am referring to intels new chipset. This chipset will completely invalidate overclocking anyway which we may see more of in the future. Buying your first PC OEM has a lot of advantages.
You know parts are all compatbile.
You don't risk damaging hardware when installing yourself.
You don't have to buy and install an OS.
You don't have to understand/set BIOS settings or memory timings, etc.
Obviously overclocking is pointless in sandy Bridge, why would you want a 5.7Ghz clock speed anyway?
Edit: A point to the OP, so you don't take this idiots advice. You say you want to keep your computer for a few years at least. If you buy a computer from Dell with a locked BIOS, once your computer becomes slightly outdated, it is slightly outdated. there is nothing you can do about it. If you build your own computer, once your computer becomes slightly outdated, can do an overclock of around 15%-20% and it will now have some extra performance to deal with games of the future. (Edit: For clarity, nothing you can do that won't cost a fair bit of money.)
In regards to the list made.
-Those things should be checked over before purchasing anyway, and it really isn't hard to understand.
-There is a risk of damaging hardware, but it's not that high as long as you aren't stupid.
-As somebody who has posted already pointed out, with all the parts AND an OS, it's still cheaper to build it yourself. Not to mention you don't need to deal with all the pre-installed crap that you more likely than not, won't use anyway. since that's added on by Dell/whoever.
-again it isn't complicated, and depending on the BIOS, there are simple options now that can make it so much easier. My MoBo, can't remember which BIOs it runs on, but it's ASUS, it lhas an overclocking menu where you can literally just select how much % of an overclock you want. It requires no understanding of how to overclock, incredibly simple.
