Your PSU probably needs to be a 550 watt Corsair or Fortron to go beyond the level of a Geforce 550 Ti, although an AMD Radeon probably uses less power for its performance at the same performance level, sort of the 6990 (dual GPU cores) class. Skyrim's GPU requirements are relatively undemanding compared to the CPU needs, which are understated for minimum, and should be corrected to
* Windows 7/Vista/XP PC (32 or 64 bit)
* Processor: Dual Core
2.3 GHz C2D or equivalent CPU
* 3GB System RAM
* 6GB free HDD Space
* Direct X 9 compliant video card with 512 MB of RAM
(and
sufficient performance to actually put that VRAM to use) * DirectX compatible sound card
* Internet access for Steam activation
The Recommended level probably should be amended to
Recommended Specs (For running Skyrim on "High" settings at 1920x1080 resolution)- Windows 7/Vista/XP PC (32 or 64 bit)
- Processor: Quad-core 3.0 GHz Intel or AMD CPU
- 4GB System RAM
- 6GB free HDD space
- DirectX 9 compatible NVIDIA or AMD ATI video card with 1GB of RAM (Nvidia GeForce GTX 260 or higher; ATI Radeon 4890 or higher).
- DirectX compatible sound card
- Internet access for Steam activation
Are you committed to using only an nVIDIA graphics card?
