Can i5-3570 or 2500 non-k handle Gtx 670

I seriously Doubt it...

Of course it will handle, both of those two cpus will not bottleneck the 670 gtx...
In my opinion if going with a locked cpu from intel, get the i5-3470, it proves to be the best value, it won't also bottleneck the card.

Lol at I doubt it yes a 3570 or a 2500 can handle a gt670 I have a 2500k and a gtx670. And agreed with dj there on the recommendation if you get a z77 board you wise as well get the k sku card however if you don't plan on overclocking get a h77 board.

My list of spec :
Gtx 670 windforce 2gb windforce
motherboard sabertooth 990fx
cooler master 750watt psu
vengance corsair gaming 1600mhz 8gb
3 120m coller master fans
cooler master 212 evo
amd fx 6100 six core processor
1080p monitor
intel 120gb ssd hard disk
1tb harddisk

I planning to change processor and motherboard to sabertooth z77 and i5-3570/2500/k

Is that fine ?

No they will not bottleneck it. Might as well get the k, it isn't much more. You could even go with a cheaper mobo.

I would save a little unless you really want the sabertooth board and perhaps get something like a ASROCK EXTREME4. You really don't gain anything from the sabertooth board other than it has gone through a ton of stability tests to ensure the product is awesome.

I agree with bigshootr here. If you look at motherboard benchmarks. They are all, umm... yea. Asrock z77 is a solid choice, then pick up the i5 K series.

But to answer your question. Nope, it won't.

what different between asrock z77 and sabertooth z77?

it wont what ? wont most out gtx 670 ?

The extreme 4 has the ability for higher memory modules where as the Sabertooth will not work with them. The SLi/CF situation is the same. More SATA ports with the Extreme4. I would say next to little which is a common thing among motherboards today unless you get a more expensive board for example something like a UP5
http://www.newegg.com/Product/Product.aspx?Item=N82E168... which has dual thunderbolt ports or a ASUS ROG board I would say that you will find little difference in boards except a few more ports a few more little things here and there but pretty much all the same.

Won't hold it back

Won't bottleneck is what he means it wont bottleneck.

Do you live by microcenter? Go for the i5-2500.

The i5 2500's are not showing up with microcenter and based on the price listing for it it would be more of a value for him to get a 3570k

Why get a older processor for the same price when he can get a intel 3570K that beats it

No I know. Microcenter normally has deals and intel has phased out that line of processors to push people into the ivy bridge stuff. Microcenter typically has super low prices on CPU's so maybe there was a deal or something.

asrock z77 can beats sabertooth z77 ? i5-2500k hard to find nowsaday

That's why I asked if he lived by microcenter... It's his decision, He could get a faster processor for the same price as what he origionally wanted...

or

He could get a slightly slower processor for really cheap $150.

It's up to him if it's really worth it.

how is it with SLI/CF does non K version suffice to not bottleneck them? tough i am sure even if not, that 3770 non k would have no problems dont you think?
