I'm sitting on a 13" early 2011 macbook pro and I can't work in logic at all... I'm trying to finsh my mix but all I get is cpu overloard errors, it is making me crazy! I'm running about 50 tracks and I've realized that there are some waves plugins that takes the most CPU, like JJP Guitars, CLA Bass and CLA Guitar. I was thinking about getting a brand new 15" macbook pro, but I don't know if that will make it? I was thinking about to upgrade it to SSD and 8gb ram, but my friend who has the new macbook pro and SSD (not 8gb ram though) even he gets overloads from time to time (also did a test with 10 channels including these 3 plugins on each channel, he got overload)... Can someone help me? I dont want to buy a 2000 dollar mac (think they even cost more here in sweden) and then still get overloads... What should I do?
