That's not to say that I don't enjoy playing remotely recent games but I don't OC the system to get higher frame rates nor did I expect it to run Crysis with graphic settings maxed out. I use recent game titles as a multimedia benchmark; if it can push a modern video game then it should have no issues with lesser tasks. (games have always pushed hardware development.)
My heaviest load these days beyond Assasin's Creed is concorent VMs. VMs are the new primary benchmark with Games secondary. I don't get much time to actually play games while VMs are crucial to my work productivity (contract and personal education). Right now, I have two seporate side projects which rely on being able to design the OS build within a VM as Development and Testing stages with Testing builds remaining along side the production install on hardware. If I could afford a rack or multiple machines at home, my setup wuld be a little different but a properly raided NAS for the house is more pressing than a "Development Studio" server.
When home, I need my workstation to remain stable so I can work on multiple VMs depending on the project or function as an application server when I'm around the house using a notebook as a thinclient. When out of the house, I need that machine alive and available as a respository and application server as needed.
The first time I had an issue was when at a clients. I start my day by going into the machine at home, checking my email through the home hosted email client then downloading anything I've prepared for the tasks that visit. I was presented with "server not responding" when I tried to ssh in and found my machine locked when I returned home. Rebooting failed during the ram init.
This last time, I went down stairs Saturday morning to find my old friend "Sir Frozen McUsless" workstation locked up. Nothing new in six months of trying every RAM bios and hardware configuration I can find plus returning bad ram under warranty.
The heaviest load was when testing ram and CPU by opening multiple cracking sessions against my own wifi trafic CAP files. Prolonged heaviest load has been by opening multiple VMs including a few Windows VMs (they really suck ram up quick). This last crash was with my single groupware VM in the background and X on the screen.
It's somewhere between RAM and GPU and I'm not unwilling to consider the latter but my pacience is pretty much exhausted having never had this kind of grief in many years of building systems in professional and personal environments. I would also be less pissed if this was not effecting my ability work; I have deadlines for these VM builds and something barely better than paper clips ducktaped together to use.
I think I'll be looking at Gigabit and Abit motherboards unless all the forums report that one of the other Asus ROG boards is flawless; giving up the external post lcd is the biggest loss. My NF7-S was a dream to build on top of.
