Now that I upgraded to windows 7 i was slowing upgrading my PC little at a time and i was going to buy more memory today. I looked at my newegg invoice and i had purchased the TWIN2X4096-8500C5DF memory 2x2gig sticks for 95.00 back in july. I click the link and now the same memory is 179.00 !! i had to triple check details and yes its the same memory. I don't remember getting a deal at the time of purchase. Is this memory really that expensive ?
