He is memory limited, not bandwidth limited. I should know know, I run into the same limitations on my own system running at 7680x1440 despite using PCI-E 3.0 16x.
When you become memory limited, the GPU has to send more information down the PCI-E bus to access the information in System Ram/HDD, which is where he sees the impact.
As for Steamroller, The Inquirer is reporting on rumor, AMD has neither confirmed or denied it yet. - I would love to see AM3+ get Steamroller, both my AMD systems (1090T HTPC and the FX 8120) will get upgraded to it if it's compatible, I just wouldn't buy into a platform hoping for a future CPU release, you might walk away dissapointed like so many when they jumped onto AM3 hoping for world-changing Bulldozer. (And thus only having the ASUS Crosshair IV support the CPU's unofficially!)
That OCZ PSU is decent, lots of amps on the 12v rail, not a bad choice.
Also Op, welcome to the PC Gaming master race, may all your games be good ones!

It looks like he is hitting both the VRAM limit and the PCIe 2.0 limit....if you look at the video at around 5:10 mark he talks about the PCIe 2.0 limit... then if you look at his second vide, where he switches to PCIe 3.0, you can see the quad SLI really fly.

As far as steamroller, you may be right. I was reading the specs on the FM2+ boards Asus just announced and maybe AMD will be utilizing only APUs moving forward on the consumer market. But if they do release FX based Steamrollers, I dont see them changing the socket. Everyone knows whatto expect from Steamroller and I dont think they can warrant a brand new platform, unless they can provide a brand new architecture that Excavator can ustilize as well.
