Don't most games run at least off a quad core processor tho now?
I really like this case : CoolerMaster CM Storm Scout
The i3 is fine for gaming, no bottleneck with it. That's more expensive case for the budget, for this kind of budget a decent case like the elite 430 will do.
Highly recommend the "If you can afford to spend a bit more" build. Most games are still optimized for dual core actually. But it will run a bit better depending on your setup. Gaming on dual cores is still acceptable and will perform great.
But for BF3 on High??? Wouldn't a dual core just not cut it for that type of play? I'm sorry I'm just new and asking a bunch of questions.
Nope, it doesn't bottleneck the cards in question, in fact for BF3 it will be limited mostly for the gpu, a 650 ti or 7770 doesn't cut it for 1080p ultra.
