Keep i7-4770K or Get i7-4820K???

Need opinions on this.
I currently have an i7-4770K/Asus Gryphon/16GB/GTX 770 setup that I'm fairly happy with.
I'm considering adding an Areca RAID card so that I can RAID 0 with (4) 250GB SSDs for awesome data storage speeds. Yes, 550MB/s single SSD speed is not fast enough. I want as close to 2GB/sec. Read/Writes as possible.

But, I know that adding a RAID card into my second PCIe slot will drop the badwidth from 16X to 8X for my main (vid card) PCIe slot, so I'm considering switching to the X79/i7-4820K platform because of more PCIe lanes.

My question is, would this be worth it?

PLEASE: Can anyone link a graphics card performance comparison on the Z87 platform with the main PCIe slot running at only 8X as opposed to the standard 16X?

Thanks,

The difference is ~1% (measurement error), I'd stick with what you've got now.

4770K as it will be faster most of the time.The extra 2 Mb cache can matter in some applications but they are few and far between. Remember you can always get a PLX Z87 mb if you want.

Thank you very much. This helps alot!
Guess I'll be sticking with the Z87 platform.
