Some bundles are good; not this one.
I advise against that bundle. $276 for 6GB of DDR3 1600? A Cooler Master PSU, for the same price you could get a better Corsair PSU? Two GTS 250s for the same price as an Radeon 5850? The $130 in savings on the bundle doesn't quite match the extra expense for some of the parts; you can get equivalent parts cheaper, or better parts for the same price, even after accounting for the bundle discount.
You can do better than this for $1350, if you're willing to take the time to spec it out yourself.
The Asus P6T combined with an i7 930 isn't a bad starting point. Add the Corsair XMS3 DDR3-1600 with the same timings as the Dominator for $180 instead of $276, and an overclocked Powercolor Radeon 5850 for $300.
You can work out the rest ...
That said, if the money's not important, and you just want an easy build, then most of the parts in that bundle are of reasonable quality, albeit some are a tad overpriced. So it's not garbage. But you can do better.
