Ok well you know what I have in my sig. The question is this guy says that by me having 4x512 is alot slower than his 2x1024. Is this true? If so by how much? Because as of right now I only have 2x512 I was just going to get 2 more but if I'm losing alot of performance I guess I'll lose my money with these 2x512 and got 2x1024. What if I had 2x512 and 2x1024 would they still run dual channel?
