Hi, Is the extra cost of an ivy bridge i5 worth the extra money solely for the better speed when couples with a 3.0 PCIe video card? I doubt I'll use the quicksync and don't need the improved integrated GFX
Thanks for reading

No it's not, but you are forgetting about the improved IPC and reduced power requirements.
Unless there is a big price difference, which there isn't afaik, then get the Ivy.
thanks for your reply, what do you mean by IPC?
ok i googled it, Instructions per cycle... so this effectively allows the CPU to run faster at the same clock rating? ivy bridge it is then
That's basically how efficient the processor is.
An Ivy can do slightly more work at the same clockspeed, it's not a big difference, but then neither is the price.
very well put, although i have a feeling the sandy bridge will start to drop in price as vendors start stocking ivy bridge
thanks
Ivy Bridge is the way forward..
so it seems, i'll definitely pay the slight difference for the newer tech
Over the next 2 years you will save more in electricity bills by going with the ivy cpu. If you went with sandy you would probably end up paying more ££ over time due to higher electrickery usage.

Are you overclocking or running everything at stock clockspeeds?? PCI-E 3.0 might be useful,but even ATM it does not apparently make a huge difference. The thing is IB has slightly higher IPC and clockspeeds,so in many cases it makes more sense unless you are getting a decent reduction on a SB CPU. Novatech actually had OEM SB Core i5 CPUs for under £120 for a long time for example. A 2.8GHZ IB Core i5 should be broadly similar to a 3GHZ SB Core i5 IIRC.
Power consumption again is not really a big deal for a normal size system. Idle and low load power consumption is not massively different between the two platforms. IB has better load power consumption,but again unless you are loading the system at 100% for long periods,the difference is not going to be very noticeable. People obsess about the CPU only,but motherboards and other system components also are important to consider too and do make s significant impact to power consumption.

Just my two cents; I have a ivy i5 3570k which is supposed to run at 3.4GHz stock, but it runs at 3.8GHz all the time!
Why go backwards if the cost is minimal? So yeah! Ivy it has to be :-)
3.8ghz is turbo mode, although some motherboards put it into turbo mode 100% of the time.
You only need to increase voltages once you get over 4.3ghz (YMMV).
My friend was debating between the SB CPU I have (2500k) and the IB (3570k), and for the £10 difference I don't see why you wouldn't...
