okay i have the base 2009 model with a c2d 3.06 cpu and a 1tb seagate. also the better gpu. I would leave the gpu alone but I want to drop this cpu into it. http://www.ebay.com/itm/Intel-Core-...623?pt=CPUs&hash=item589074050f#ht_3445wt_907 It will work, but Is a guide available? I also want to put this ssd into it. http://www.ebay.com/itm/Samsung-470...064?pt=LH_DefaultDomain_0&hash=item43aa39e268 I can mount it correctly, but will it work? would like to know if anyone has used this model in a 2009 iMac. I have the ssd in hand so it is the upgrade that I am really going to do . THE cpu is more of a might as well.
