Would there be any significant bottlenecking with this setup? I'm willing to start a completely new build but I would rather hold off on it for a little bit longer.
you still have a fast 4 core cpu at 2.66 you know notebooks run at 2.4G Mobile i7 and use 2x GTX 780M in SLI
? which is close to GTX 780 ?
Dont worry about Bottleneck much
