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.

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


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.

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?


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).

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.

We don't have Asus RMA in Brazil :p 
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.


Brazil, it still has the warranty on the shop you're going to buy, if the guy that's selling it, doesn't have or transfer it, it might be better to buy in a shop.

The 650$ kit is from an online shop called MercadoLivre (it's completely safe, but depending on the seller there might be no warranties).
If I went to a physical store, it probably would be around 750... But still, I'll take a look at that, even though we're almost getting the price of the i7 kit doubled :o
