Results: Grid 2
To say that the Grid 2 High Quality results from Don’s $1300 PC are incredible would be an understatement: I’d love to toss my drive on his machine and take another run at it.
We do know that this benchmark becomes CPU- and DRAM-bound at lower resolutions, and find it tough to believe that Nvidia’s architecture has that much less impact on these components. It's implausible, but still possible. I’ll let him have those numbers and keep my fingers crossed that a card I have coming my way will confirm them.
Those DRAM and CPU bottlenecks go away at higher settings, and that’s where we see reasonable performance scaling. Paul’s little $600 PC pulls through with 39.2 FPS at 4800x900 (and without overclocking), even though it only needed to reach 1920x1080 to be rated a success.
