Counter-Strike: Global Offensive
Valve's Source Engine derived games and mods have a notorious history of stability and performance issues on AMD Bulldozer machines, requiring AGESA microcode updates to be pushed through motherboard BIOS releases to make things right (probably related to the anti-cheat memory address randomization routines). The AMD Trinity performs a tad below the Ivy Bridge but still commands acceptable framerates, although there will be dropped packets/updates when playing in 128-tickrate competitive servers where a stable >128fps is ideal.

Resolution: 1920×1080, AA: 8x MSAA, Filtering Mode: Anisotropic 16X, Vsync: Disabled, Shader: Very High, Effect/Model/Texture/Paged Pool: High, Multicore Rendering: Enabled
Both AMD and Intel can serve up a smooth zombie shooter, but you probably can have more of the undead on the screen with the blue camp.
Street Fighter 4
No discernable difference here, with Ken keeping up with Ryu.
