Default Time to buy an i7 920 before its discontinued?

So the i5 is going to kill off the low end i7 range ie. the i7 920.

The i7 920 in terms of cost vs performance is a no brainer when compared to the 940 and 965 which I don't find justifyable vs the performance.


Obviously the i5 is a cut down chip and won't have as good performance as a 920.

Is now a good time to buy a 920 while the prices are about 175ex, it certainly wipes the floor with the Q9550 and Phenom 955. I can imagine many will be after 920's likes hot cakes once there gone - so they should hold or even increase in value?

It does? In what universe?

10% difference at best for triple the price? (given that with your setup you only need a 9550 but you have to change motherboard, CPU and ram for an i7 920)...

I'm sorry, but right now, you are not making any sense. Definitely not worth it.

If you're in the market for a good quad and do NOT have the ability to just drop in a Q9550 or Q9650, then absolutely now is a good time to get an i7 920.

Remember too, the current i7's utilize triple channel RAM whereas the new ones (as well as the i5's) will just have 4 slots on the mobo and support dual channel RAM.

Any news on when the i5's are supposed to actually launch?

There way more then a 10% increase, video encoding is 15mins vs 35mins that the qx9650 to decrypt a blu-ray 30mins tops on qx9650 over 1hr 24gb-30gb that did benchmarks use to be around 18k now hitting around 32k, overall the system just perform way better, and this is coming from a guy who own the qx9650. I did these tests myseft because I thought the samething you did.

It not just the CPU it the chipset the memory controller is just good and the QPI on the CPU, jump on while you can, you won't go back.

Being you are only running a q6600 you will be like WOW!

A Q6600 at 3.2Ghz... My main interest is games and the C2Q still delivers. In the OP's case, he'll have to spend a fortune swapping 3 parts when he can just swap CPUs.

And actual reviews show nowhere near what you are claiming, video, image whatever...

Care to provide any proof for your claims, besides "i tested myself"?

I toyed with dropping in a 9550 in my current rig and hopefully getting it to around 3.6 ghz... but I decided against investing in a dead platform.

And while the C2Q is great for gaming now I really feel it will be an instant bottleneck once the GT300 shows up.

Well, considering that one will upgrade to the GT300 for GPU limited scenarios, how will you be able to tell?

In CPU limited scenarios, both CPU architectures will perform great or terrible. The experience equivalent is the same whether its 60 vs 80fps or 15 vs 20fps, either great or terrible. In GPU limited scenarios, it doesn't really make a difference does it?

That's my reasoning, and that's why I'm not upgrading. Maybe when the CPUs out offer 1.5 the performance of current C2Q at a decent price, then I will upgrade. And that's gaming performance...

Well I'm basing it on the fact that when SLI is entered into the equation the i7 has a pretty healthy performance advantage. Not to mention a D0 is practically all but guaranteed to hit 3.8Ghz if not higher just adds to the equation.

Got the 965 extreme got it clock at 4.2ghz with 12gb ram with SSD's on water, won't be fair if I benchmark it, better to find someone who has the 920 overclock to 3.2ghz and run test clock for clock . almost always better to see for yourseft, I thought the same you did at one time and try a freind of mines system was blown away, for what ever reason just runs overall smoother then upgraded after seeing that.

SLI or not, the situation is still the same. If the game is heavily CPU limited, SLI will offer no advantage. Both architectures will choke. It's either 15 vs 20fps again. If its CPU limited but not heavy, the i7 architecture will push more FPS, yes. But it will be 80fps vs 100fps or 100 vs 140fps (because of SLI) again. If the game is GPU limited, the game will run twice as fast (in ideal scenarios) regardless of the CPU...

I still don't see how this CPU is worth its money. Unless its a completely new system out of nothing or changing from a really old system, I'd just recommend to people to get a C2Q... Its like going from a GTX260 to a GTX280. It doesn't make any sense...

Anyway, that's how I see it... I've made my suggestions, that doesn't necessarily mean I'm right or anything. Only stated what I think and gave my reasoning. Other than that, it's the OP's money and only he can decide how to spend it.

Tony.

I've got my Q9550 overclocked to 3.6 if anyone with a 920 @3.6 wants to post benchmarks so we can compare it would be interesting.
