I am taking apart an old E-Machines t6522 and I uncovered an ATI Tuner called the Theater 550PRO. In my gaming rig, I put the old 80mm fan from the emachines. Can I have the TV tuner and my r9 290 together? I doubt it but I just want to make sure. Also, I found 3gb of DDR ram in it. Can I use that with ddr3? Thanks!
