I never said you didn't know what a bottleneck was, I said you weren't aware that GPUs always bottleneck CPUs, learn to read. And I only insult you, everyone else I just talk to. You lend yourself to being insulted by insulting me, simple as that. Stop talking as if you know everything about me, cuz you don't know shit fool.
You don't have to go around wasting your time writing an essay for a reply. If one of the dual cores is working on AI (which multiplayer games like UT don't use, unless you're playing with bots, which is no fun) that leaves one core to run the game, which is no more powerful than a single processor, and is infact weaker. Thats a stupid example, so lets move on to an example where a game in totally divided on the two processors. Two problems; GPU bottlenecking and game FPS limit. Either way, having a stronger processor won't help. Either you'll be stuck at a certain FPS with the GPU, or you'll have reached the game's FPS limit. Either way, your performance doesn't increase with a Dual-Core processor.
If you write another essay, I'll laugh at you.
