Quad Core Gaming Pointless? Waste of Money?

Okay honestly I am not sure but, from the gaming aspect I see quad core as a marketing thing for gamers... in otherwords really overrated, and I kind of find it weird that it took me this long to figure it out on my own, I probably was blinded by all the marketing of manufacturers like alienware. Just take a look at their systems on their website http://alienware.com/product_pages/desktop_all_default.aspx ... they're all mostly quad core.

I haven't heard of many games that are optimized to run on Quad Core Processors hell even 8 core systems. In fact I beleive alot of games run better on Dual Core processors as opposed to Quad and so forth.
Its kind of like spending money on a Ageia physX card that only is designed to run with a handful of certain games.
I can get a powrful gaming system for the price of some of these Quad Core proccesors.

Does anyone disagree or agree?
or know any games that are optimized to run with a 4 or 8 core CPU? - I only know one or two.

Gaming = waste of time and money.  Buy a console for the cost of a video card that will last you many years and just play it when you get the urge or need a tad bit of relief from pursuing meaningful endeavors.

Building your own PC won't be 40-60% cheaper either, maybe a tad bit, if that.

Logic: Large computer manufacturers deal in high volume and receive lower prices on their components, you don't

The main savings that come in when people build their own PC is from pirating their OS and shit like that.

Alienware is vastly overpriced though.  Macs aren't, they are priced low-mid range.
