Ivy i5 vs Sandy i7

[Dagoliroberto]

Hello everyone.

My current config is:
AMD Phenom II X4 965 - Corsair A70
ECS A790GXM-AD3
2x2GB Corsair 1333MHz
2x Seagate 1TB 7200RPM (raid 0)
Corsair TX650M
MSI GTX 570 Twin Frozr III @ 900/1800/2000

I have to decide between getting a i5 3570k + Asus P8z77-v Lx kit for 650 dollars and a i7 2600k + Asus P8z68 Deluxe used (7 months of use) kit for 500 dollars. I'm not into video editing or anything like that, I just want a processor to stick with me for around 3 years, just like my old Phenom 965 did. However, it is indeed starting to bottleneck my 570 on BF3, especially on bigger maps like Caspian Border, so I think it's time for it to retire... haha
I wanna point out that I will stick with my old 2x2 Corsair 1333MHz RAM for some months, until I can get myself a pair of Low Profile Vengeances... I was going to get the i7 right away, but after reading a lot about the new tecnologies the Z77 motherboards can offer, I got a little skeptical. How much will PCI Express 3.0 for example affect the performance of rig through the years? As I said before, this i7 should stay with me until 2016 or so. Until then, I plan on getting a GTX 780 next year.
So, what should I do?
p.s. Please don't tell me that I can get those for waaaay cheaper. I know that, but I don't live in the US.

It seems it's for mainly gaming, get the i5-3570k, it has faster cores, with the ivybridge architecture improvement, the hyper threading of the i7 doesn't help in gaming.
Also you get a motherboard with newer features, the i5 supports pcie 3.0(could be useful for future cards, for now it isn't).
Nobody can predict how long it will last either the i5 or i7, specially for 2016, both might be obsolete by then, get the cpu has you need as of it now.

3570k for gaming, as ht in gaming today doesnt really get utilize. barely.

3770k for editing and design of course.

 

[Dagoliroberto]

So, getting the i5 3570k is worth it because of the new technologies, even though I will have to spend 150 dollars more and still end up with a slower processor?

 

[djangoringo]

how much is the cost of the i5 and the i7 plus the motherboards ?

i7 2600k + Asus P8z68 Deluxe ($500)

 

[djangoringo]

Well, then get the i7, it's cheaper, but it's odd, it's usually more expensive, is it because of the price of the z77 ? or the i5-3570k is much more expensive ?

Nah it's mainly because the i7 is used. hahaha

 

[iceclock]

get the 2600k since its a better bang for bucks and z68 vs z77 not a real world difference.

 

[djangoringo]

Nah it's mainly because the i7 is used. hahaha

Make sure it's from a trusted source, i usually don't recommend used things, but if it's cheaper and from a reliable source, it might be worth it, if not get the i5 at least is new.

How much is PCI Express 2.0 gonna hold back a GTX 780 or a HD 8970?

 

[iceclock]

if its from ebay or someone u trust whynot.

if its untrusted than skip that option

Nobody knows, until there's a review of one of them(and for the reports, only by the end of the year), but more powerful cards in the future might take advantage of the pcie 3.0 bandwidth.

 

[iceclock]

i doubt its gonna change. a 7990 or 690 runs great on a 2.0.

i find that theres 2 things. in theory performance and real world performance. in reality what it says it should perform at really isnt what it performs at.

 

[Dagoliroberto]

I'm buying from a trusted user, with over 10 other negotiations with other users.
Will that difference between pcie 2.0 and 3.0 take more than 20% out of the cards performance?

 

[iceclock]

no. u wont see any real world difference. videocards dont even utilize fully 2.0 for that matter.

For now there's no difference, in the future no one can tell, but you can expect future cards,to some day, to take advantage, for now they simply don't.
If it's from a trusted vendor, you might get it, also worth mention, there's the haswell intel cpus coming in June(official).

 

[Dagoliroberto]

Okay, so I think I'll get the i7. Thank you very much Mary Harron and Tarantino fans! hahahaha

 

[smokeybravo]

I wouldn't buy a used CPU or motherboard... Anything else maybe, but not those.

Why?

 

[djangoringo]

If the motherboard is also used you don't have a warranty, and if the source is that reliable, i'd seen people with more rep selling crap.

 

[iceclock]

i agree dj just saying as of today its gimicky 3.0 and 2.0.

but future will use it im shur.

but by that time maybe pci 5.0 will be out lol

 

[smokeybravo]

Why?

No warranty, can't RMA it if it doesn't work, they could have burned it up overclocking it. There are just too many reasons. The 3570K is going to be better for gaming anyway. You'd be investing $150 in some peace of mind knowing you can always swap it out if it doesn't work, and it's better for what you're going to use it for anyway.

 

[iceclock]

lol the 2600k is just as good in gaming. but no rma unless the warranty is transferred.

 

[Dagoliroberto]

We don't have Asus RMA in Brazil
But as I have more successful negotiations then he does, he'll be the one sending me the product. I'll only pay him only after testing the whole kit.
