Upgrading from i7 to i5

post #1 of 13
Thread Starter 
Say I have a buyer for my i7 920 and RIIE and decide to upgrade to 2500k.

I haven't been following sandy bridge at all.
Do they have a stepping like i7 and C2Q series? (D0, G0, etc) If so, which is the better one?

What are some good motherboards for the 2500k?

As far as I can tell the only difference between 2500k and 2600k is the cache and hyper-threading, is that correct?

Don't do it, More like a side-grade.

But, If you really want too, Get the 2500K, And yes the only difference is the cache and HT.

IT would be better to wait for Ivy Bridge next year. You really won't need the extra performance unless you're doing video editing or something.

For anyone interested in such things, I've been tracking progression in 3DM11, from my 920 into my 2500K. All numbers are with the EVGA GTX580 in my sig. I know there are plenty of other benchmarks where 2500K excels, and it does use less power. But for most it probably is indeed a sidegrade to a very slight upgrade.

i7 920 @ 3.6 = P6459
2500K @ stock = P6281
2500K @ 4.0 = P6495
2500K @ 4.5 = P6597
2500K @ 4.8 = P6641 (this last is not quite apples to apples, I finally started fiddling with my memory here and have it at 1866 vs 1333 on the other 2500K numbers above. Very loose timings though. Close enough.)

Don't do it.. I have an I7 930. I'm not upgrading till something good comes out. You'd be wasting money. Last gen I7's are just as good as new i5's to me.

Unless its something that supports quicksynch, the 2500k (@ 4.5GHz or so) isn't going to be much faster at encoding than an i7 930 (@ 4GHz).
