As most of you probably know a 2.13 GHz MBA requires you to shell out $300 for the 256 SSD and an additional $100 for the processor... ending up $400 more than a 1.86 GHz. I have already made up my mind about getting 4 GBs of RAM and is now trying to decide on the processor. Given that I have absolutely no need for the additional SSD space, is $400 worth the 0.27 GHz difference? I have researched this topic and in many other threads the overwhelming opinion was "no" (and probably more so in my case because I am blowing $300 for the pre-req SSD which i will never utilize). However, according to a credible benchmark (can't remember the source for this but can dig it up if you guys really want it... I think it was Macworlds?), the 2.13 GHz performed "10%" faster overall than the 1.86 GHz. Being a tech newbie, I have three questions: 1) how exactly does a 10% increase in "benchmark" performance transfer over to real life? (i.e. will I notice this difference at all doing things like web browsing, email, iTunes, Preview, Word, watching videos, which comprise 95% of my usage) 2) This is a more tech-related question... does the 10% increase in speed apply to everything you're doing, or does it only matter if the task you're trying to run requires high processing power? (i.e. 10% might be evident if you're using rendering software but will all of that power be throttled if you're just opening a web page?) 3) I plan on playing SC2 on low-medium settings. Will the additional 0.27 GHz of processing power improve gaming performance? Or is it really just more dependent on RAM and GPU... Thanks guys!
