Advice request: What should I wait?

Noone to help, me?

Your request is a bit vague.

But, assuming you need a full system, buy these now:

Case
PSU
Optical Drive
Monitor
Keyboard
Mouse

Wait for:

CPU
Cooler
Mobo
RAM
GPU

I agree that this is too vague but what is the primary use for this system going to be? The thing is if you wait for Ivy Bridge (which I've heard isn't supposed to be released until Q3 next year) you'll keep waiting for the best parts to come around, you're better off picking from what's available now and then upgrading as you see fit.

PCI-e isn't going to change much. The graphics card vendors know this and they won't see a lot of happy customers if they release new products that are only available to people with certain boards. PCI-e x 2.1 is the standard for now, and most cards - even the newest ones like the 7970 will be compliant with this form factor. You'll be safe here for quite some time, and you won't see a whole lot of improvement from what's available now.

It's like using an SB-E system - it's the latest and greatest for sure, but the latest and greatest anything will be sure to cost you deeply.

Whether new card and CPUs are coming out or not, I don't think it is a good idea to buy parts over several months.

If a part happens to be defective, you may be left out of the return policy.

Is cash availabilty an issue? Guess so from the incremental build.

Maybe go for i2500k and mobo now as well, I didn't realise Ivy Bridge was so far off.
Maybe worth hanging back on GPU so when new items arrive next year the current models drop in price - hopefully give you better bang/buck.

But difficult to be precise without knowing the use as g-unit says.

Will cost Ivy Brigde as Sandy Bridge?

The thing is Intel's already admitted that Ivy Bridge is going to continue the 1155 socket design and that Z68 and P67 motherboards will make use of the CPUs with a BIOS flash (similar to what AMD did with the FX series).



Yeah but the thing is no one's going to know yet what Ivy Bridge is going to cost - is it going to be a consumer line that will replace SB? Will it be a performance enthusiast line like X58 or X79? Something else entirely? Everyone knew about SB-E, which are really glorified Xeons, but the performance difference really wasn't that great over the 2500K, 2600K and you basically pay a lot more for not much of a justification.



It's also difficult to price using hardware that doesn't exist yet.  



I totally agree - that's the worst possible way to buy a new system.
