CPU bottlenecking GPU's?

I have 2 XFX radeon hd 6770's in crossfire mode, and an intel core i5 2300 overclocked to 3.4ghz. I would like to know if my CPU is bottlenecking my GPU's, and if it is, what are your suggestions for what CPU i should buy.
Thanks.

  1. Oh no way not even close. An i5 2300 should handle Crossfire HD 7970s ( OK maybe a little there ) but it sure is not holding back 6770s.
  2. Seconded. I don't think 2 x 6770s would be bottlenecked by a 2300.

    I wouldn't try 2x 7970s or even 2x 580s on it, though.

    Especially not on games like BF3 that require a lot from the processor in general.
  3. that's not a case every 2 gpu's run fine on i5 SB series there is no sign of any bottleneck so don't think about bottlenecking you are 200% fine on these two gpu's

    good luck!
  4. Thanks for the replies guys, I really appreciate it.

    x2 7970's on an i5 2300 or 2500k

    well the 2500k is also there at that level, lets say out of level 100

    i5 2500k is at level 85, while a 7970 x2 would be at level 98 or something along the line, but well to max things out pretty well and to keep them even and balance i think a i7 2600k would fair well although i'm convince the i5 2500k is a very powerful cpu too, im using one my self
