Most modern PC games (with a few exceptions, like ArmA II and GTA4) run just fine on a decent dual-core CPU, provided that you have a good enough graphics card. The Athlon II X3 435 is the best "price:performance" value in CPUs right now for a gaming PC; if you absolutely must play one of the few CPU-bottlenecked games out there, however, grab a Core-i5 (and, in the case of ArmA II, a SSD.) But most of you out there will only need the 435.
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
