I wouldn't buy a prebuilt if I were you, unless you don't miind about the cost. It's much cheaper to buy all of the individual parts on a site like www.newegg.com and then either assemble them yourself, or if you don't know how/can't be bothered, get someone else to do it for you.

A good friend of mine once bought a cheap, prebuild pc on ebay. It was crap. It looked pretty good on the paper, but the components didn't interact well and the whole system crashed a lot.

Also it would be interesting to know what you wanna do with the pc. If you have gaming in mind stay away from intel dual core E**** processors, those suck at gaming and are overpriced.

Eww... whoever is selling that "Extreme Gaming PC" is veeerrryy bad...
He only has a 550W in that desktop.

Just build one yourself, it's much cheaper and this way you can get the best for cheap. I bought a prebuilt recently. It died within 3 months. Got it fixed 3 months later, and died just recently again after 3 months.

Now I am about to build a new one...

So like other people have said, just build a PC, or get someone to do it for you.

Dual Cores aren't really worth it anymore.
Like everyone else said, build your own. Learning to build one is a very valuable skill to have. If you need help building one let me know, I wouldn't mind walking you through what to look for.

Do not waste your money on a dual core. They're being phased out already.
