But many of those same benchmarks show Core 2 Quad nipping at i7's heels as well. IF FPS gaming at all becomes part of the equation, then it will be almost impossible to tell an i5 from and equally clocked C2Q. RTS games will indeed show i5 over C2Q, but we'll be hard pressed to catch many of those benchmarks since site's like this one have it stuck in their heads that FPS games are the only ones that matter for performance :/
I suppose I'm looking at the more multithreaded apps for things such as rendering and what not. If you look at those benchmarks you see that Core 2 is far behind i7 because of it's support for 8 threads and much quicker memory access. Since i5 will have those same 8 threads and IMC, I see no reason why i5 won't be significantly ahead of a C2Q in those same applications.
Now obviously if the OP indicates that his computer is for gaming and he won't be using any heavily multithreaded apps then ya I would say just get a C2 now. But I haven't seen any indication as to what he will be doing anyways.
Keep in mind, i5 will be always slower then i7, so any benchmark that shows i7 beating Core 2 Quad, take that result down a bit and you have a good idea of i5. Intel will NOT allow i5 to eat into the i7 performance. Because of that, it will be hard to feel any difference between a Core 2 Quad and an i5 machine except in the most heavily threaded apps. Since there are not many of those, on average they (C2Q, i5) will be strikingly similar in performance overall I expect.
Obviously it won't be the same as the i7, but I find it very hard to believe that in a well multithreaded rendering app that a Core 2 would even come close to an 8 threaded processor. In my opinion, common sense tells you that the processor that can handle twice as many threads will out perform the one that can't.

How many well multithreaded apps are there? Not many. Most apps are poorly multithreaded (wasteful code being the worst offender) to not multithreaded at all. Even many of the well threaded apps don't scale above 4 threads. Most don't scale above 2.
And you cannot count the 4 virtual cores as full cores.They are not. Your assuming that Core i7 performs like an 8 core CPU when it does not in any way. It SIMULATES an 8 core CPU, but the total performance would be closer to 6 cores then 8 in the very few apps that can actually use more then 4 threads.
I really think you shouldn't set yourself up for dissapointment on this one. You should take my attitude on it since if I'm wrong, it's a GOOD thing, if your wrong, you'll be bummed out. You don't wanna be bummed out, do you?
I havent found the need to upgrade from my non hyperthreaded dual core E8400 yet.
Can you name the apps you think we would benefit from an i7 with?
I'm not going to start naming apps, look at my sig, I have an E8500, I don't do any rendering or any thing else that would potentially use over 2 threads. My information just comes from what I have read in reviews. You can easily find this information on your own with google.
Hmm so i7 owners can talk about what they like and no one is allowed to pull them up when they post useless info?well go and stick with your core 2's while us i7 users have fn with ours. this thread aintr about how useful a fucking i7 is. its about WHEN it will drop it price. way to go out of topic as per usual.

I wasnt the one off topic to start with, I was correcting someone that already was.
If you are going to pull people up on the posts they make, at least get the fundamentals right..
Thats a decent answer, one of the better ones I have seen to validate i7.
Useful applications are limited but at least people can now decide if the above applies to them and thus if i7 is of benefit.
Thanks for your time to answer properly
Perhaps CamaroZ28 can add his experience to cover his earlier comments?
I already told you that I don't own an i7, so therefore I can't provide any information based on experience, the info I provided was based on reviews. I could sit here and link a bunch of reviews all day, but the fact that 99.9% of the people who read this thread won't bother to click them makes it a pointless use of my time. I have no need to "defend" myself or "cover" my comments when I know myself that I bring factual advice. On that note I'm unsubscribing this thread as obviously the OP has no intention of replying.
Actually, X58 boards support dual and single channel modes. What they do require is DDR3.Yes; X58 requires three sticks of RAM compared to only one or two with LGA775; however, given RAM prices today, the impact of that upon the total build cost is minimal and dropping.
Taking what I said above, an i7 system can have as little as 1GB. Not that it's reasonable (or advisable!) to, but it's completely possible.The biggest issue with i7 is that it doesn't really allow skimping on *software*; a minimum i7 system will have 3 GB of RAM (throw in graphics, and you're pretty much blowing past the ceiling for a Windows-based x86 operating system). LGA775 lets you get away with 2 GB or less

when will i7 prices start to drop?
answer = when AMD finaly release a cpu thats on par with the i7 in every way and is cheaper in price OR if AMD release a cpu that is better and faster then a i7.
untill then intel have no reason to put prices down.
Why wait for i5? You might as well buy a Core 2 Quad Yorky today, the performance will be pretty much the same. i5 is the lower end Nehelam, and Nehelam is only made faster then Core 2 Quad by the very things that make i7 faster then i5, 3 channels of memory and QPI. If your going to give up those 2 details anyway, why wait? That level of performance is already available today and very cheaply so.
Keep in mind, i5 will be always slower then i7, so any benchmark that shows i7 beating Core 2 Quad, take that result down a bit and you have a good idea of i5. Intel will NOT allow i5 to eat into the i7 performance. Because of that, it will be hard to feel any difference between a Core 2 Quad and an i5 machine except in the most heavily threaded apps. Since there are not many of those, on average they (C2Q, i5) will be strikingly similar in performance overall I expect.
