bottleneck performance?

@ooshima: my board doesnt support SLi, can i put my vga there?

Does not need to support SLI. As long as your mobo have at least a 2nd PCI-E 3.0 slot that supports at least x8 speed then you can plug there and try.

Ya... I see leaked benchmarks any where from 4-8% or 15% IPC gain from haswell. I'm a little mixed on continuing with -E platform because I haven't seen increase gaming performance switching between 4 to 6 cores, it's expensive to upgrade frequently and it's nearly a year behind latest architecture. DX12 games may take advantage of the extra cores. Depending on further benchmarks I see with DX12 and skylake if I'm not impressed I may wait it out till Skylake-E, which will probably be around 2nd half of 2016.

The thing is -E series chips aren't primarily for gaming. In fact the i5-4690K is very sufficient. Most games are on single core performance rather than multi-core performance and thus -E chips won't be able to beat Devil's Canyon in terms of single core speed. Haswell-E in generally can't be clocked as high as the i7-4790K.

As a matter of fact, my i7-4790K is a golden chip and was able to clock at 4.8GHz @ 1.24V stable. On the other hand, I didn't get lucky at all with my i7-5820K (which I use for content creation purposes) which I have to settle for 4.2GHz @ 1.24V too.
