Should I upgrade to 3570k?

So I made a computer last year and as I got smarter and actually put some effort into research...I realized a couple places I went wrong. Primarily, my motherboard and CPU. I have an Intel 3550 and an Asus P8B75-V motherboard. I'm wondering if it'd be worth upgrading at all to something like an Asus P8Z77-V Pro and 3570K since I would probably overclock. I have someone offering to buy my mobo and cpu if I go through with it. Would it be worth the cash? Or would it be better to at least upgrade to a Z77 board? Another thing I might add is I'm looking at upgrading when Skylake, DDR4, PCIe 4.0 and the new SATA comes out.

So yeah..should I just stick with what I have and wait or is it worth holding on? I currently just game and other odds and ends.

Specs:
Asus P8B75-V
Intel i5 3550
MSI GTX 660Ti OC
8gb GSkill DDR3 1600MHz
850W gold cert. Antec PSU
Samsung SSD (Windows boot)
2 500GB HDDs (1 is storage and other is Ubuntu)

That's another thing..since the board I'm looking at has more than 1 6Gb/s SATA port, would that make a difference vs. the 3Gb/s ports I'm using for my HDDs? My SSD is hooked up to a 6 Gb/s

You can OC non-K chips to 400MHz higher than whatever its highest Turbo multiplier is (but only on Z77 boards not B boards). At 4.1GHz, you shouldn't need to overvolt it (i5's have a lot of stock voltage headroom typically from 4.0-4.4GHz depending on chip). But even then a Z77 board can over/under volt any CPU - even totally locked down i3's & Pentium's. You don't need a K chip to adjust VCore.

Depends on how you use it. With a Z77 board but keeping your 3550 CPU, you could get a potential 4.1GHz OC (despite being a non-K chip) as follows:-

Normal Turbo Boost : 3.5 / 3.6 / 3.7 / 3.7 + 4-bins limited OC (400MHz) = 3.9 / 4.0 / 4.1 / 4.1 (load based Turbo). With "MultiCore Enhancement" you could potentially run it at 4.1GHz for all loads.

I have a non-K 3570 and I can do 4.2Ghz permanently with a Z77 board:-

With a 3570K chip you could probably squeeze another 300-500MHz out of it depending on cooler but whether that's worth it above 4.1Ghz depends on what price you get for your 3550.


Pointless upgrading for the future IMHO. Buy what you need today.


SATA 3 vs 2 is slightly noticeable on SSD's, but not mechanical HDD's.

So we can overclock non K CPUs but we just can't overvolt it right? So in this case, would a z77 board be a good change? Because I know the B75 chipset limits RAM to 1333MHz. I wouldn't mind spending some extra cash to upgrade to the Z77 chipset if I could see a boost from it. As far as my knowledge goes, I could see it being a worthwhile upgrade

You wouldn't need to overvolt to achieve the limited overclock. I did the limited overclock on my i5 2400, but left turbo off. Might go into the bios and enable turbo to see how it does. Changing up to a Z77 board like the Z77 extreme4 is a worthy upgrade to get the most out of your chip. Also you can do SLI or CF if you desire with that board.

If you kept the 3550 CPU but upgraded the motherboard to a Z77 with MultiCore Enhancement, you'd get around 15% higher clock rates (3.5-3.7GHz to 4.1GHz), and the ability to use 1600MHz RAM plus whatever other features it gives (CrossFire, etc). Whether that's worth it depends on what price you get for your existing board / what other features you want.

As for buying a 3570K chip as well, you'd probably gain about another 7-10% (say 4.4-4.5GHz OC) over a 4.1GHz 3550 OC, which probably isn't worth the price. I have an i5-3570 (non K) OC'd to max possible 4.2GHz, and I've never felt the need to move to a K chip just for an extra 200-300MHz. The only other thing 3570K offers is faster iGPU (HD4000 vs HD2500) which is a non-issue if you use a GFX card.
