skyim isnt a cpu game, only uses 2 threads...so aslong as you are over 3.0ghz your fine,skyrim uses pre 2006 tech cpu wise lol.
try bf3, or dragon age 1..or 2, ghostbusters i can so many more that want more then 2 cores now adays, that why i have a 4 core overclocked to 3.5ghz, 6 core isnt needed for todays gaming but quad is.
as for that gpu.....wow....all i got to say lol.
go on kijiji or craigslist w/e is better in your area, go pickup a ATI 5850 or ATI 6850 OR NVIDIA GTX 460 1GB(OR 785MB) for $100. 10000000000000000x better
