Lynnfield i5 or Bloomfield i7 ?

Hi,

I've already posted about an i7-920 build and I was ready to buy, but I'm waiting for the new nVidia/ATI cards since I learned that the 5XXX serie was coming.

I'm thinking running at a 1920x1200 resolution and *possibly* upgrade at 2560x1600 when monitors will be a bit more affordable.
When I say possibly is that I may go for a XFX/SLI configuration so, like this, I can run on a better resolution. =)

What I expect from a CPU:
- Friendly overclockable
- Can support a XFX/SLI configuration (w/ou limiting the performances of both cards)

From what I know the i5 loses far behind the i7 about that, but do you think that the bloomfield worths its 200-300+$ (cpu price diff/mobo/rams)?
All I want to do w/ my computer is being able to play FPS at good/high 1920x1200 resolution on a 24' monitor.
Actual budget for i7 platform w/out monitor is 1400CA$ (double GTX 275), but how much can I save
with a i5 platform?

I would opt for the socket 1156 Core i7

Here is an article regarding crossfire scaling on P55 motherboards:

Finally, I would absolutely not get dual 275s, start with a single 5850/70 and see if you really need to go dual.

I see, I was confused by this sentence, so I thought I'd play it safe and advise against it

One request: a link! (mainly because of: "CPUs perform better" but because of the 5 FPS too). It's not that I don't believe you but I'd like to see the benchmarks.

From what I know, the performances of the stock I5 is almost the same of the stock I7 (I7 wins because of HT). But once you overclock the I7, it's game over for the I5.
