Yeah, I have GTExp. I think it’s required. It autoupdates when it wants to, or at least prompts me to update.
I put this computer together originally because I had waited so long for Duke Nukem Forever and was GOING to play it without any hardware issues. Yeah, game sucked. But, even with new components and a Radeon HD 6850, the game was stuttery. And that’s even if I bumped it down to low resolution and turned off effects. That points to some kind of inherent issue, but I don’t know enough to know what it would be, though the mobo, CPU and the memory are the only things I haven’t switched out since then.
The CPU is fine IMO and unless your sys isn’t seeing the memory or it’s some ungodly slow memory, then that mobo has to be the issue, Especially if as you said there was info that came out later about a problem of any kind.
Fortunately thats the cheapest upgrade. Even an older z87 (which I have) will pass that much data with no problem.
