IS haswell cpu's worth it?

No.

IB > Hasfail

The 8350 is equal to any 3470 or 3570 out there...

Yes they are worth it. Even though it is a " Tock" in Intel speak, Haswell was not intended to dramatically improve the computation power of the cpu core. The target was better integrated graphics and improved power efficiency. Haswell chips especially in the notebook segment achieve this and Iris and Iris pro integrated graphic solutions are doing a great job.

As for compute power refer to an AnandTech comparo or an xbit review and indeed haswell is not a major improvement in this department but still is faster. a 14 second improvement over a 3770K by a 4770K in sorensen squeeze pro does mean something.

There are always some people who start calling an Intel socket "dead" as soon as the first cpu from that socket is announced. I fail to understand the kind of upgrade path people look for over say a 2600K when it will easily feed most of the top end GPUs out their in multi gpu set ups (there is an article comparing an 8350 and a 3770K running a 7970 CFX set up i think and both of the cpus actually struggled a bit)and will not bottle neck in games yet to to be released and those which would be released in coming 4-5 years.

Most people build a machine going for the best cpu that their budget allows for and then using the rest of the budget to buy parts that can be updated later. And most such people do not worry about upgrade path that much. Not to mention, a board one buys today, will badly cap the potential of a cpu one would buy say 4 years down the line. For every new socket, Intel releases plenty cpus so that it can address as many price points and you are ensured that unless you buy the absolute top of the line available cpu from a particular socket design, you will have an "upgrade path".

Forte, I believe you should not listen to people saying 1150 is a dead socket or that 4770K is not worth it. Yes, a comparable SB cpu will give comparable performance in most day to day stuff including gaming and you can decide which cpu to go with but haswell is definitely not a failure and is better than previous architectures. then again, that's just my opinion.

good luck

Okay so you want the following stuff in $900

1. CPU
2. mobo
3. Ram
4. GPU
5. HDD
6. PSU
7. Case

Add or remove any components so that we have a clear idea and then we can help you out with a build.

share those mock ups...will make stuff easier for us.

Check this out, add SSD, the motherboard could be little pricey, you could lower it to Asrock Z77 Pro3 (this system is for slight overclock user), if not, other good B75 or H77 will suit you, I have no idea with these kind of board:

SSD's are not an absolute must though they would speed up your system but not game play. I could come up with a build for around $1200 with everything minus the OS. Since am in office right now, I wont be able to upload it. Will do that as soon as I get home.
