atomicweasel :
Mainly for a gaming desktop of a total budget of £500. Im a bit of a newbie and all this confuses me (first time I'm making a buying a gaming PC). I just want the one which can run games well and the two ones I'm thinking of are intel i3 4340 (3.6 Ghz) dual processor and then an AMD A8 6500 quad processor (4.1Ghz). PS I can only get it from PC SPECIALIST (http://www.pcspecialist.co.uk/pcs/) so feel free to have a look.
Hi there. You're better off going with the intel i3-4340. It has two threads per core, so 4 threads. That means it "kind oif" acts like a quad core. Anyways, it has been shown to be quite the good budget gaming CPU

Also, it's for the latest socket from intel, so if you want to upgrade later on, you have a lot of options. The AMD CPU is a FM2 socket, which is basically at its end now.
Go for the intel based!
