920 to sandybridge

Anandtech are running the tests with no AA/AF so not very good indication of real world gaming where you will have AA/AF on. Crysis is not showing much difference in performance with the K chips over the older i7/i5, remember the K chips will be running with turbo mode on so 3.8Ghz and others chips are clocked nowhere near 4Ghz as Johny's 930 was. I guess the only benefit for gaming is where you run three GPUs like johny is, you will see better fps the faster the CPU, for everyone else with one or two GPUs there is no benefit going to sandy from a high clocked i5/i7.

Raven, thats what I think in essence and put very well by yourself...

My personal 2 penneth..

If you are on C2D

SB = Great Upgrade

If you are on S939

SB = Great Upgade

If you are on i3

Get a 750 for the value

If you are on I7 920 or above and are overclocking

SB = Severe case of upgraditus.
 
My i7 930 was overclocked to 3.8 gig 24/7 but i ran it at 4 gig for benchmarking and the sandy bridge at stock clocks gave higher fps in the games i play on my rig.

The sandy bridge is 3.8 with turbo so i was seeing a gain with both cpu at same speeds but the i7 p30 would get the advantage of running higher fsb and clock for clock sandy bridge is faster.

If you want to compare overclocked cpu the sandy bridge will destroy the old i7 as it overclocks much higher with many members here hitting 5 gig or higher with the sandy bridge chips.

I advised the op to buy gfx card or cards instead of new cpu as i believe he will get a bigger boost going that root but make no mistake the new cpu is faster and i can see more fps in my games.

This clearly shows the performance gains in games that sandy bridge has over the older i7

Some games show no differences, others showing improved FPS I would put down to the turbo mode on the K chips kicking. In real world gaming with AA and a good res the CPU is speed is less important except if you game with multiple GPUs where you need the GHz to keep feeding the them.



When we start to crank up the detail and turn on AA, what you see is a heavy focus on the video card. What that means is that even with big speed increases on the CPU like the 980X at 4.2GHz, big gains aren't always seen.

Simples, if you games with an i7/15 at 3.5Ghz or higher it would be silly to go to sandy for gaming unless you're like johny and need the GHz to feed three GPUs, even then you're not alway going to see big gains, especially when you crank up the IQ settings.

sorry dolan - didn't mean it a bad way - just would be useful for us all to see the 'actual' gains as opposed to percieved gains.

Most of the benchies I've seen of SB in gaming on the web refer to gamin at 1280x1024 - like who the hell plays at that resolution these days lol ;) Hence why games being GPU limited (especially at higher res) is the norm.

With regards to SB overclocking - 5Ghz is not the norm - its an exception. 4.5 Ghz is more like the REAL results people are getting once they take stability into account (prime for example)

i7 > 4Ghz
SB > 4.5Ghz

.5Ghz worth dropping £100+ or so on? don't think so (that figure is from selling an i7 setup for a SB setup)

I've been checking prices on x58 stuff over the last month and it's not too bad. I saw a 4ghz i7 920, UD5, 6GB xms3 bundle going for £400 at auction (not sure what it finished for, but that was the 13th bid iirc)

The pros for moving seem to be mainly:

Extra performance (how much is debatable)
Lower temps,
Higher clocks,
Lower power consumption,
Perfect for single gpu owners (no need to pay extra for 2x16)

The thing is for gaming, it's a good platform and x58 is still worth a bit. However come x68/lga2011 I presume it won't be worth as much (particularly tri channel 6gb) as it'll be superseded. For rendering, encoding, production orientated software or for enthusiast multi gpu setups I'd say wait for lga2011. Don't get me wrong, it's still fantastic for rendering, encoding, etc for people that rely on getting things done quickly for work. However, I believe they'll see far better gains come the enthusiast platform.
 
If LGA2011 seriously kicks 1155's butt the upgrade itch might come back!
It would be best to sit tight until Intel's flagship is released.

In terms of bandwidth and cores it seriously will! However the more cores=more heat=lower clocks? Please correct me if I'm wrong :(. For multi gpu setups it's the best platform, however the concern is would you prefer a higher clocked quad or a lower clocked hex core for gaming.
 
well thanks for all the advice , might be best to hold tight on the s b for now but i appeciate the conversations :)

im off to look at gpu's cheers all

This is not the CPU you are looking for /waves hand mysteriously.

I so want to upgrade from my Q6600 but my PC does everything I need it to :) the money has gone on nicer things, like a bike and eventually a holiday :)

don't be stupid mate, you'll see very little difference upgrading to sandybridge. Get a better graphics card! Listen to reason, not instinct!
