Hey Folks, So I'm about to buy some new memory but have hit something of a snag. This memory is for a new rig that I will be buying parts for in the coming week or two and I am planning on getting my feet wet with more in-depth OCing. I'll likely will be using the following... Intel I5 2600K MSI OC GeForce GTX 560 Ti (Fermi) 1GB (2x running in SLI) Mobo undecided, probably the P8P67 (maybe M) DELUXE or PRO, not really sure Corsair TX750W (thats a definitely as I already have it) and as for memory it will be one of these two: Corsair Vengeance 8GB (2 x 4GB) 240-Pin DDR3 1600 or Corsair DOMINATOR 8GB (2 x 4GB) 240-Pin DDR3 1600 But the DOMINATOR is specs 1.65v and the Vengeance specs 1.5v. Is there benefit to choosing one or the other? The DOMINATOR is a fair amount more expensive but has all the same specs (latency, timing, XMP, Dual-Channel, etc) I'm a little stuck on this one. From what I've read going with the Vengence is probably the better bet as it has a lower voltage rating, but if so, why is the DOMINATOR kit more expensive? Any advice?
