I am shopping for a new computer and I want the largest cache size possible. I've found a Dell with an AMD Phenom II X6/9MB of cache. I only understand the basics of multicore technology, and the research I've been doing online suggests that current software and operating systems are not yet able to take much advantage of it, especially anything beyond a dual core processor. I'm wondering if 6 cores could actually slow things down. Would something like a quad core with 8MB of cache be a better choice? Thanks.
