Hey... I am in the market for a new (first) iMac and I have a really difficult time deciding which one to get. I am a casual user. I use the mac for work (writing, running some websites, excel) and a little bit of gaming (primarily civilization V). I have seen the retina screen in real life and it is pretty, but I am not sure it would make that much of a difference to me. However, it seems that the base model is pretty decent. If we ignore the display and only think of speed and stability (which is the main reason I want to switch), which of these configs would be best: Non-retina: * 3.5 i7 * 8 GB Ram * 256 SSD * GTX 780M 4GB Retina: * 3.5 i5 * 8 GB * 256 SSD * M290X 2GB The price is pretty much the same (the 'old' imac is a little bit cheaper).
