I'm looking to make a minor upgrade to the mid 2009 2.26 core2duo. Right now it has 4 gb of ram and 320 gb 5400 rpm hard drive, I was thinking of either upgrading my hard drive to 7200 rpm or would it be worth it to upgrade to 8gb ram which is only $65? I'd rather go with a new hd and maybe even get the seagate momentux xt hybrid but if the ram would be more noticeable then I'll go with that for now and get the hdd later.
