I just bought an iMac 27" a week ago, I feel that the iMac is underpowered and could use RAM upgrade. I know SSD will make it even faster but it is still expensive. So my main priority is upgrade RAM first. I found this, corsair 8 gb(2x4gb) from amazon at 43.99. Is that the cheapest price for 8gb? I'm not sure the quality of corsair are good or not, but from the reviews it's seems good. http://www.amazon.com/Corsair-1333mhz-PC3-10666-204-pin-CMSO8GX3M2A1333C9/dp/B002YUF8ZG And for HDD, I am considering upgrade it to SSD, are there any cheap SSD @ 256GB or 500GB? Thanks!
