Yeah same here I have a seagate momentous something like that. 5400 rpm 3.0gbs and it scored a 4.5 nothing to impressive but now i get a three. Im installing the new ide driver from NVIDIA now ill tell you if that works.
? which did you install I went for the 32 to ensure compatibility, even though i have 4 gb of ram. My graphic card shares most of the other gig anyway.
