which one do you think will be better for flight sim ivy bridge or sandy bridge extreme

Do you have any benchmark to show what ivy bridge can do, if so I can tell you.....just kidding.Starting from the fact that almost every new CPU platform is better for FSX I'll assume the ivy bridge will be the one to beat, we'll have to wait and see.

Ivy Bridge is just a die shrink of current 1155 chips. Sandy Bridge E will be a new platform, socket 2011. Think of Sandy Bridge and Ivy Bridge as 1156 for now and Sandy Bridge E as 1366. It's too early to tell which will be better for FSX, but probably whichever one clocks higher. With that said, it probably has little relevance as we should be expecting Microsoft Flight about that time (+ or - 6 months?). Hopefully Flight will be able to take advantage of more than 4 cores, at which point Sandy Bridge E (which will have 6 and 8 cores) will probably be the better choice.

SNB-E will offer similar performance gains over SNB as socket 1366 i7s did over socket 1156 i7s - which is virtually none. SNB-E is not a new chip architecture, it's a wider system interface. FSX doesn't care about the system interface once you get past a certain point (which both socket 1156 and 1155 are past). Bottom line: IVB will be faster than SNB-E for FSX, especially since it will overclock even higher.

Ivy Bridge is just a die shrink of current 1155 chips. Sandy Bridge E will be a new platform, socket 2011....

Why do you think there won't be an IB Socket 2011? (Although I would guess it will likely be released after SB Extreme Socket 2011)Cheers,- jahman.
