Not an argument, I would think {I do anyway} stuff like this sheds light on the subject. Interesting discussions. That said...
SSD Review - T/H {omitted} or {who knows what} the testing rig -> duh the MOBO has NO SATA3! Testing SATA3 SSD?!
I'm guessing a $1,000 SATA3 Card/RAID which every $1,500 or $2,000 rig needs.
$2,000 Build - I've been always frustrated with T/H or any {site/pick any} that on a $2,000 rig that you'd spend 1/2 on a GPU + DDR and everything remaining is more-less junk ($2K with $35 cases! - come on/not this past build); something to skew the Benchmarks ONLY a/k/a nonsensical in the "real world." That's what the drooling public wants - benchmarks. This last build performed horribly compared as I recall to the May Build. My {everyday rig} w/o the CF is $1,600 - also on 9 of the 10 copies of it I am using the ASUS P6X58D-E vs the GA-X58A-UD3R (rev 2) -> that ALL BSOD with SSD + RAID 1 - another T/H Winner!
Futuremark {3D Mark Vantage} - the OP asked {gaming benefits + I can't decide between a i7 930 or i7 870} well in particular that tests BOTH CPU/GPU -
http://en.wikipedia.org/wiki/3DMark
I think somewhere there has been confusion between folklore and bitter reality.
"My bias," we all clearly have them, is in 2/3/4/4+PhysX arena of which 3/4/4+ you'd make a fool out of yourself arguing anything than X58. For the OP "Future Investment" either purchase 1 great GPU or 2 mid GPUs and later add a third when prices drop, and instead look at the + $16 i7-950 vs the i7-930.
Last, regarding "tests" and CPU 3D Mark Vantage easily I can explain the disparity some people {T/H} guilty too of pushing a CPU to the point of failure to achieve a result. Futher, some use
Liquid Nitrogen to cool the CPU/GPUs, that's why you need to "LOOK" at the list; hence the link. Bottlenecks - anything slower than the fastest part {CPU, GPU, MOBO, DDR} is indeed a bottleneck on some level.
On my Gaming rig, I mention "Profiles" - I don't leave it always running @ 4.6 GHz, I have others all the way down to "stock." However, with Koolance I sometimes leave it at 4.6 GHz for a week.
Hope this helps!
X58 Gaming Benefits - Improved bandwidth of CPU/GPU/DDR3 Tri/Hexa-Channel, over all architecture {reduced/eliminated USB3/SATA3 bottlenecks}, PCIe lanes speeds X16 {2X 16X} with 8X minimums through 4-WAY, faster CPU support.
