I want to know if it is worth upgrading from an i7 860 to an i5 2500k.
I just busted my old 1156 motherboard but the processor is fine. The lga 1156 motherboards are more expensive compared to the 1155 motherboards so what should i do????
I am from India.
SPECS:
I7 860 (Coolermaster Hyper 212+) stock 2.8GHz
ASUS P7P55D-E PRO (Not working)
4 GB Vengeance RAM
MSI GTX 580 TF2
Thermaltake 750W PSU

Budget 15000/- Rs (approx 350 USD) (+ how much ever i get for selling the i7 860 if i sell it).
Only used for gaming.
Thank you.

I was in a similar situation recently. The cruddy heatsink on my 1366 i7 920 came unattached from my motherboard on one side and ended up frying the CPU. After doing some research, the cheapest it would have been to replace the part without downgrading would have been $250, which seems like a bit of a waste considering a 2500k is running $220 and 1366 is a dead end, socket-wise. So I went ahead and jumped to 1155 and a 2500k, and couldn't be happier.

Obviously, it's been a more expensive initial investment right now, having had to replace CPU, motherboard and memory, but I feel much better about being a bit more future-proof. I'm also gaining some of the new tech that's been incoporated, like SATAIII and USB3.0, so I'm enjoying that. The mhz boost has been noticeable, as well, as I wasn't able to get any OC out of the 920, the 2500k went to 4.2 without a hiccup.

Anyway, as far as your situation goes, it's a bit different although I'd probably go about it the same way. If I could get by with a fairly cheap replacement on a single part without a loss of performance or features, I'd probably go that direction. If I was feeling like I was getting ripped a little bit by paying a premium for an evolutionary dead end (in this case, your 1156 socket), I might go ahead and skip to 1155 if you have the resources to do so. At least in your case, you don't have to get a new ram kit.

Wow sorry for your loss bro, that is one of the reasons I never use stock coolers they are junk!

For the OP I would just go 2500k and sell the 860!

That was the worst part, it wasn't stock! :( I had gotten a decent deal on a TT Spinq and thought it would do ok, even though the reviews ranged from ok to meh. What it does have is the same type of pins to connect to the motherboard that the stock intel cooler does. I should have know it wouldn't be as stable as something with a real backplate, but I went with it anyway.

Ah well, live and learn. For this new half-build, I went with a Xigmatech Gaia, and been suitably impressed. Even with the overclock, the highest temp I've hit so far is 60c, and it usually runs mid 30s. I feel much better about trusting my CPU in it's installation over those plastic pushpins TT used.

yeah the 2500k and MSI mobo in my sig, which is far from basic, was only $325 up front plus it has a $20 MIR.

I've seen TT Spinq it all show and no go.

And I would still classify it as junk.

I like the choice on the new cooler I recommended one of those to a friend of mine and they were also impressed.

Yeah, the Gaia's been pretty great so far. A lot cheaper than the CM Hyper212+ currently, as well. I want to install a second fan on it to see how well the push/pull setup does for temps.

Thanks for the quick replies.

Just to be sure the i5 2500k is faster than the i7 860 cuz some of the tests show that the i7 860 is faster........(only talking about gaming)

i7 860 only turbos to 2.93ghz when all 4 cores are utilized.
i5 2500k ships with 3.3ghz stock clocks (and turbos up to 3.7ghz - although maybe someone with a 2500k can point what the max turbo is with 4 cores loaded).

Add 15% IPC improvement, and that i5 2500k @ 3.3ghz = 3.8ghz Core i7 860.

That's a 36% performance improvement without overclocking over your stock 860. :p Overclock the 2500k to 4.5ghz, and that's about as fast as a 5.2ghz Core i7 860 in games.

Of course in games like Crysis 2, Metro 2033, Witcher 2, you'll be bottlenecked by the GTX580, not the i7 860. But technically speaking, 2500k is faster than the i7 990X for most games. Not bad for a $220 CPU.

Your mobo is broken. So, I don't see how you can wait. Especially until IB comes along. That won't be until next year, from what we are told.

I would think that your 860 is perfectly fine. The 2500K wouldn't be a noticeable increase in performance. For now, just get a new mother board.

Unless BD just whoops ass big time, I'd use the 860 until IB comes along and see what the best platform is at that time.

3.3ghz vs 2.8 clocks (+ turbo modes). Thats where the performance difference comes from rather than the 'fantastic' new architecture SB is made out to be.

.... While the clock speeds add +18% of performance increase, 2500k is 15% faster per clock than a Core i7 870 at the same clock speed and 2600k is 17% faster.

Not to mention an overclocked 2500k consumes less power than the 860 at load and reaches well into 4.6-4.7ghz range while 860 tops out at 4.0ghz for the most part.

And Sandy Bridge architecture is fantastic considering the chip embarrasses an overclocked Phenom II X6, while consuming 44% less power at idle and 46% less power at load in those overclocked states.
