that 5650 is a gem in laptops since its a 5730 thats factory underlclocked, which I have and its stable to 684 core and 1096 memory, and thats gives me 34.1 GB/s bandwidth which is approching 460M territory. And that AMD is a tough sell over the I-5 430-560M chips since most games only use dual core chips and the hyperthreading is better than 2 unused cores. so Gaming the I-5 is better, for work like catia/cad + video encoding get the AMD. http://www.newegg.com/Product/Product.aspx?Item=N82E16834220796
is by a stretch best performance/dollar buy you can get atm. The 360M is only 8% slower than 5870 which overclocked can give you a cheap 460M with a I-5 which has a supported PLL code to OC the CPU too. So in essence with some tweaking you can have a 750$ 3.2ghz dual core /hyperthreaded with a 460M. Buy a mommentus XT 500g and a 8gig ram set and enjoy a 60+ fps on any game at 720P unless its crysis then 45 fps tops.
