I'm about to order an iMac 27" as a family computer and could do with some advice on BTO options. This is my first ever apple product, and it's going to have to last a while. The two main uses that set the boundaries are - my own interest in gaming (mostly strategy / role playing) , and - my daughter studying Graphic Design -so wanting to use the Adobe Creative Suite. Apple are suggesting that the top 27" would meet our needs without upgrades. Which would obviously save some money. However from reading some other threads I'm wondering if upgrading both the GPU and CPU might not be a good idea. Fusion being a bonus if finances stretch to it. Thoughts appreciated ?
