Opteron bottleneck GPU's?

What opteron is rlly the question u should be asking. Games prefer a higher clock speed than most server cpus come with, as well as a good single thread performance over a server cpus multi thread performance. A sixteen core 2.8Ghz 6386 SE in games prob wont be the same as lets say the 6308 quad core @ 3.5Ghz lol Really if its a current gen opteron a bottleneck should not occur at a decent clock speed as they are based off bulldozer and piledriver

shouldnt be a problem depending on what gpu u deceide to use.
