I'd pick the Silverstone OP/DA line over the GameXStream. Again, the 600W and 700W GameXstreams suffer from serious ripple on the 12V rails under heavy loads. Plus, I don't like multi-rail designs... single is a better solution in general.
There are several models in the OP/DA series, and their performance is very good:
$148.99 (750W, single 60A 12V rail)
: $174.99 (identical to the OP750 but modular)
$229.99 (850W, 70A 12V rail, modular)
$329.99 (1000W, 80A 12V rail)
And a DA1200 should be coming soon
