You missed the best option between the 2 you listed. Grab the i5 760 for $170 instead.
Now you can grab a low voltage $90-95 DDR3 4GB kit instead of $130 DDR3 6GB kit and a good p55 mobo can be had for $125 vs. $200 for i7 930. Socket 1156 760 makes the "full i7 930 + mobo + 6gbs of ram package" poor value imo.
So let's add this up:
$30 (CPU savings) + $75 (mobo savings) + $35 (ram savings) = $140 cheaper than i7 930.
I'd get the i5 760 no question since @ 4.0ghz it will last far longer than the 640. It will definately survive another 3 GPU generations at 4.0ghz, while 640 is already slow in certain games (like SC2) due to lack of cache.
All fanboism aside, there is not a single CPU from AMD that can compete with an overclocked Core i5 760 (or even a stock one) unless you are doing some specific video / encoding work. The X6 may prove to be better in the future as more programs become multi-threaded, but the 640 is still only a quad-core.
So you're saying you've seen fresh installs of Win 7 vs. Vista SP2 side by side the same day with such hardware disparity and Win 7 really is that much more efficient?Outside of an Atom (sigh), pretty much even the cheapest of the cheapest CPUs these days will run like absolute champs with almost all common Windows use when combined with basic specs like a decent 1TB HDD and at least 4GB of memory. It helps that Windows 7 is the first new edition of Windows perhaps ever that is MORE efficient than the previous release. I've seen Dual-Cores with 2GB run better on Win7 64-Bit than Quad-Cores with 4GB on Vista (not running raw cpu benchmarks, just responsiveness in Windows and launching apps/startup/shutdown/that kind of thing).
The i7 should be MUCH faster.
The Athlon II X4 630 (2.8Ghz quad-core), scores around 12,000 stock on the Nuclearus benchmark. Coincidentally, so does my friend's overclocked E5200 @ 3.625Ghz.
So the X4 630 is equal to an overclocked Intel Core2 dual-core. The i7 930 should blow it away.
5 years ago, the new top of the line CPU's were Athlon X2 and Pentium D dual core. Both of these are weaker than today's entry level dual core Pentiums and Athlon II X2.
Based on that, I would say that in 5 years you may find that you would appreciate the extra oomph that the i7 would give.
As RS points out, the best deal might be the i5 760. Nearly as powerful as the i7 930 in most cases, and cheaper total platform cost because S1156 mobos are cheaper that S1366.
Its' easier to upgrade the video and SSD in the future.
BTW, before purchasing the Radeon 5770, you might want to look at an Nvidia GTX 460 768mb. The 5770 is nice - I have no problems with mine - but if you can catch a GTX 460 on sale, it will be only ~$30 more expensive, and is a hella performer at that price.

I think you're twisting the truth a bit if not making things up and thus unfairly perpetuating the myth that Vista is an impotent OS, when in reality Vista and 7 are actually very close. While I'm sure its been proven that Win 7 is indeed more efficient, and even some extreme cases such as guys getting it to run on Pentium 2s, but there's no way I take a dualcore/2GB/Win7 over a quadcore/4GB/Vista (assuming equal niche duals/quads; obviously an E8600, i3-560, or especially an i5-680 would wipe the floor with an entry level quad in every day tasks, regardless of OS)
