Gaming tests
Gaming has always been responsive to higher bandwidth.It still seems as if higher latencies erode the performance advantage of faster RAM and driven clock frequencies.
Virtually indistinguishable performance between Corsair's XMS4400 and XMS3200XL makes the former more useful in cases when the enthusiast has no other option than to raise FSB/driven clock in order to attain a faster CPU speed.
Finally, a win for XMS4400 memory, albeit a minor one.
