Hello, I am currently running 2 XFX Radeon hd 6770 1gb's in crossfire and have an intel core i5 2300 overclocked to 3.4ghz (stock 2.8). Is my CPU bottlenecking my crossfire 6770's?
the i5 2300 is on the same level as B and C as for A = too old and weak = it would bottle neck your CPU, it's the same with the others although the 6950 (C) is a little bit higher than the i5 2300 but it should not post any problem
nope! your cpu is absolutely right stuff for SLI'ing or CF'ing your cpu even at stock speed can handle both of these cards you should be fine ok! No need to be worry.
