Hello, i current have (had) 2 systems, one was a htpc with a 1055t and onboard graphics, and the other a 2500k and a gtx 580, the power supply blew and killed the mobo and gtx 580 of the 2500k system, now, my question is, if i should buy another mobo and a 7950, or buy a 7970 for the 1055t system, i never really needed a htpc in the first place. lol.
