Hey Guys. I could really use some advice. I don't know much about apple hardware and therefore i could really use some advice. I have an old iMac 27 inch from late 2009 that i want to replace with an iMac 21,5. I just have some problems understanding the outcome of the different hardware... Will i be able to notice the better hardware with what i use my computer for? Currently i have a " ATI Radeon HD 4850 512 MB" in my 27 inch. The new iMac will get either 2.9GHz Quad-core Intel Core i5, Turbo Boost up to 3.6GHz or 3.1GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz Graficcard in 27 inch ATI Radeon HD 4850 512 MB the new 21,5 inch iMac will get. NVIDIA GeForce GT 650M with 512MB. I basically use my computer for watching movies, playing a few games (civilization 5, left 4 dead 2 and so on) and for work (word, excel). Currently civilization is a bit laggy during the end of the game. Do you guys think i will get a more smooth running computer, without lag issues? The grafic card isn't that much better, so im hoping the CPU might be what will save the computer.. but as i said i really don't know anything about this hardware.. so i hope you can help and advice me. by the way. Can you recommend the fusion drive? Thanks.
