It's done well with Oblivion and Fallout 3. Running them with no slow downs with enough FPS to use Qarls texture pack and natural environment mods.
I know there is no official system requirements out yet. But I'm wondering if anyone else out there are curiously looking into upgrading now that Skyrim has been announced? This is my system:
CPU: E8400 dual core at 3.0Ghz
GPU: NVIDIA GTS250 1GB GDDR3 (was originally a 9800gtx but it died)
4gb GDDR2 Ram at 800Mhz
It's pretty much mid-range now but it was the top of the line back when I built it. I'm assuming the average gamer on here has a build similar to this. Will you be upgrading? Or are you confident enough that this build will run the game fine?
