I grabbed a 08 cmp from the E-waste pile, with a post-it note "dead video" taped to the top. While im not sure if the installed ATI 2600xt works, a brand new 5770, sealed in original non-static bagsc, was in the box of goodies next to the 08 cmp. After a good tear/down and cleaning, the cmp 08 booted up to the desktop, running on 2gb with memory issues one FB-DIMM card. Swapping the RAM, the issue follows the bad 1mb stick. For a production coordinator, this box will be more than enough CPU power to handle my enterprise OS/X graphics coupon rendering app. What's the fastest / cheapest FB-DIMM the 08 can handle and where is the best source in 2016?
