Hi dudes, I want to buy an 20" imac or an 13" macbook both running NVIDIA GeForce 9400M graphics but from what I read someone said that these macs won't be compatible with snow leopard's openCL feature. Is that true? And my final question for you is should I wait until snow leopard launches to buy my new mac (new models coming) or is it ok to buy em right now? please reply ASAP cuz I'm in a hurry. THANK YOU!
