Will it be a bottleneck?

post #1 of 6
Thread Starter 
Hey guys, just wondering if an i5 760 at 4 Ghz would bottleneck a AMD 6990? At full HD. I would be pretty sure it wouldnt now what if the processor was at 3.8 or even 3.6?

No, it will not. That's a great combo. It shouldn't bottleneck even at 3.6GHz, though. i5's run graphics cards the same as i7's, and I'm sure i7's at 3.6GHz are okay.

How do you actually know if it will or won't bottleneck? Is there some kind of calculation or formula that states this?

Open up MSI Afterburner, and play a game. People like to use Crysis, because it takes a lot of GPU horsepower to run the game. There is an ingame overlay which displays how your GPU is being utilized, in percentages. If the usage stays at a constant 95%-100%, you are not being bottlenecked. Any lower, and you may need to overclock more or invest in a better CPU.
