Hello sorry for the milionth thread on this topic but..
Will this computer run skyirm on Max 1024 x 1280
Powercolor ATI Readon HD 5450 1GB DDR3
AMD 5000+ 2.6GHz Athlon X2 Dual Core
2GB DDR2 800 mghz RAM
Windows 7 Ultimate Directx 11
Western Digital Caviar 500 GB
cpu is fine, most games barely tap into the second core of processers, maxed games on my computer only take around 2.2 GHz so you should be fine with the cpu.
video card will live through it to, try to check the core clock on it and mem clock on the GPU (video card.)
you need better RAM, 800 Mghz is pretty slow for computers, try finding at least 4 GB of 1200Mghz RAM, at the most you need is 8GB for RAM once i getn there i never see a diffrece of 8GB and anything higher.
lastly what is the LB2 Cache on your processer. this can change the idea of how much RAM you need?
Edit:here is my build ( this is costly though)
intel i5 2500K 3.30 GHz quad core with 6MB L3 cache
corsair 8GB 1600Mghz DDR3 RAM
western digital caviar Black 500 GB Hard Drive.
EVGA GeForce 550 Ti 1 GB GDDR5 X2 ( gonna SLI before Skyrim)
