I would say mostly that waiting would be a better idea if you can. But I would wait till ivybridge is released and then buy snadybridge. the difference in performance between the two is not going to be much in this case, and intel has already delayed the ivybridghe release date a couple times. The specuialtion is that the delays are only because they can and want to sell through snadybridge inventory, not because it is not ready for release. I can direct you to a podcast that I listen to from a hardware review site. They have been saying what I have parroted above.

What I have read is the CPU performance is going to be close to Sandy however it have built in USB 3.0 and better graphics compared to Sandy. It will also go to 22nm architecture and switch to the "3d" design meaning there will be much less heat and be more energy efficient. What I have been reading is as of now the expected announcement for release will be April 23rd with the CPU's in stores immediately.

I personally have held off waiting for Ivy to do a self build, however if you are looking to purchase a prebuilt machine Sandy could make sense since once Ivy hits expect sales on the Sandy machines. You could also pick up Sandy processors at a discount in 3 weeks as well for a self build. From what I have read for pure performance it will be about a 5% increase Ivy over Sandy but Ivy does have other advantages. If price matters wait a few weeks and grab Sandy on sale, if not as much Ivy should cost around what Sandy currently does so could get "latest and greatest".

Ivy Bridge isn't a new architecture, it's the same architecture as sandy bridge (except the iGPU), but just die shrunk, 22 nm instead of 32.

Because it's just a die shrink, it's not going to show large performance gains. The advantages of the die shrink are mostly shown as power savings. The TDP is 77 W instead of the 95 W on Sandy (IIRC). Intel is changing some things (3d transistors) so it's expected that there will be a 5-10% performance boost depending on application. This isn't that much. However, the on-die GPU is getting a new architecture, so the new HD4000 (and 2500?) will be decently faster than the current on-die GPUs (around 50%). This isn't that important for desktop users (where a discrete GPU is common), but will be nice for laptop users who wish to forgo a discrete chip so they can save money and improve battery life. Especially coupled with ivy's lower power requirements. If you want a laptop, I'd wait. They might be expensive though.

Don't expect the prices on Sandy CPUs to drop when Ivy is released. In the past, intel has not done this. The first generation core-i series (released before sandy) have not seen any price drops, even though they came out in 2010. Intel just doesn't drop prices because they release something new. Retailers might drop prices of complete systems because they need to clear stock, but it won't be intel dropping the price of their CPUs for system builders.

As for upgrading, it comes down to asking yourself the questions "Does your computer do everything you want, fast enough?" If the answer is no, then go ahead and upgrade. But if everything is sufficiently fast, you might as well hold of if you won't notice much difference. What do you use your computer for? Typically office tasks don't require much CPU power. But if you're editing videos, gaming, or doing some sort of power task, it might be worth looking into an upgrade. Basically, are you satisfied with your computer? If no, upgrade.

Ugh, onto a third.

Anyway, Ivy should cost the same for each chip (the i5-3570k is the only one that changed, $9 more expensive than its i5-2500k equivalent), so if you're building yourself, it's only a couple week wait. However if you're looking to buy a complete system, retailers might charge more because it's newer. And may discount sandy to make room.

If you're really looking to save, you could look into used parts as enthusiasts sell off sandy to buy the brand new ivy.

I just went from a core 2 E6550, which runs at 2.33, to the Corei5 2500k. Ivy Bridge is not worth the wait. I got a deal that Microcenter runs oftern, buy a 2500k, get 50 off any motherboard hat supports it. I ended up getting the 2500k, a microatx board that was the best u can get in that size, 8 gigs of new ram, and a small htpc case for under 300. Get the 2500k while it is still in stock this cheap. the z68 boards are worth it, the i5 and i7 sandy bridge are worth it, you will upset if you waited and spent more than you had to to have the latest and greatest. Ivy bridge is just a slight upgrade to sandy. I have been building PC's for over a decade if that helps any.

Also, do not wait. Sandy is as low as it going to get, and retailers are clearing them out to make room, so prices will actually go up. Also, this only applies if you doing a build yourself. Buying prebuilt is not worth imho, if you can turn 20 or so screws and follow directions, you can build a pc.

i wouldn't bother. Get what you need now, at the price point you can afford. The only thing that happens with a new chipset is things shift a little on price points.. but 1 generation apart isn't going to shift all that much. unless you're looking to build, literally a week or two before the release of something new - don't bother waiting.
