Report returned my dell...what to get now? in General Discussion Posted August 2, 2007 but doesnt that 511mb (256mb dedicated) graphics card have hypermemory...the same thing you hated about your otehr laptop? i'd go with the dell...the one with the 256MB NVIDIA GeForce 8600M GT yeah thats true. i dont mind hypermemory or turbocache as nvidia calls it. i just wanted a minimum of 256MB dedicated. The card on my returned dell only had 128MB dedicated memory. Here's the site that shows the specs of the two 8600's. The one with turbocache has a faster gpu but less stream processors i dont know what this means. http://www.nvidia.com/object/geforce_8600M.html UPDATE: The benchmarks on notebookcheck.com say the 8600m gt is faster. I think the GT uses turbocache too but not as much.
