okay, after googling around it seems the stock cooler isn't really that good, so I will probabbly get an aftermarket cooler of some sort.
the Accelero X1 apparently doesn't fit the GT's (but it does fit the GTX's, weird)
the Zalman VF900 is a possibility
are there any others worth mentioning?
I will probabbly get the VF-900 with the blue fan, to match with my current theme:
it costs $58
currently, my CPU cooler has 2 x blue LED 120mm fans on it.
Forsa 7900 GT - $420
Zalman VF900-CU LED - $58
total = $478
