I need to upgrade the ram in an imac g5 that I just acquired. I know it takes pc3200 (it's the non-sight version). But, I don't know anything about memory timings, CAS latency, etc. Does it really make a difference, or will any pc3200 work? Specifically, will this work?: http://www.newegg.com/Product/Product.aspx?Item=N82E16820178101 It's the cheapest pc3200 I've found, by a pretty significant margin.
