Mr Pizza, do you mean that it is a waste of money for CURRENT games? Would an i7 future-proof you a bit?
Not really. The big difference between an i7 and an i5 is multithreading. Most games aren't very well threaded so it doesn't make a difference. For a purely gaming build an i5 is the better value.
I still don't think an i7 is a bad choice. The processor doesn't cost that much more. The motherboard and ram cost more, but you get what you are paying for. The motherboards for the i5 have a very limited PCI-E bus that will bottle-neck high end graphics setups and will prevent you from adding high speed PCI-E expansion cards later.
LGA 1156 is also as good as dead. It will be discontinued Q1 2011. LGA 1366 is at least staying around until Q3. Some people are still hopeful for new processors on LGA 1366 before then, but I wouldn't count on it.

Your stated objective in this thread is a gaming computer. IIRC, in your original thread you said you wanted an i7 930 configuration.
The i7 930 will perform *slightly* better in gaming, but not noticably. This is why the 750 is a better gaming "value" because the i7 cpu and mobo cost (at Newegg prices) $150+ more than the i5.
Both have 4 cores, the i7 will run 8 threads. The extra four threads are not the same as four more cores. Oversimplifying, using the same core for two threads isn't nearly as effective as putting those two threads on separate cores.
Because of this, the i7's performance is even better in highly multi-threaded applications. There are very few highly multi-threaded applications, but it might be somewhat helpful in video editing, if not now perhaps in the future.
If you are looking for a gaming computer that will do some video editing fine, the i5 750 is the best value. The i7 930 is faster, perhaps not noticably (gaming) and unimportanly (video editing).
You can look at this comparison of benchmarks for the i5-750 & i7-920 both at 2.66GHz to see the difference hyperthreading makes:
* All game benchmarks are faster on i5-750 because it was released later with some enhancements.
* Most other benchmarks are faster on the i7-920.
I have a similar rig, slightly different brands but same basic thing. I use 7 Pro64, with a Raptor 160G for operating system and a TB hdd for data.
The biggest difference is my twin 9800GT silent pipes (fanless). I know there are better cards, but 2 of these handle anything you can throw at em, and with a 30cm case fan this is the quietest, coolest, most reliable pc I have ever owned. Just make sure you have the space they are huge cards lol
I am permanently overclocked - stable on 4.09GHz with stock cooler at 38C idle, 55 or so when you really get it pumping.
You want a computer that will last you for 5 years, you have one. BUT there will probably be something amazing available then that wont run on a 'mere' i7 ( holographic tv? lol ).
If you sell the house and buy the best money can buy, like a 4x6core nehalem multi cpu setup or something mad like that.. you still are not going to ensure against that possiblity. Todays very best is next years value buy..
Go with the setup you have, you cant go wrong. Dont mess around with an i5, hyperthreading is great for some things already and may or may not be more useful in the future. Doesnt cost much extra so why bother limiting yourself? hey and it always looks good when software shows you have 8 cpu's
