I tried making this a poll, but the option has been turned off. Anyway, heres my situation: i have a 17" iMac with the standard 256 MB. From what I've been hearing here at MR, you can never have enough ram in OS X. My question is this- if i were to buy more, how much should I buy? I was thinking 256, but will 128 suffice? And how much of a speed difference will I notice? I don't run too many heavy duty apps, occasionally photoshop and such. Although im only 15 and money is quite a big factor, I think I'll be buying from crucial, they seem prretty reliable, unless anyone recommends any other reseller. I've been living on ramseeker.com for a while and am just not sure what to do. Thanks in advance for any suggestions.
