Can my pc run Skyrim on ultra settings with 1600x1200 resolution?

Here are the specs, don't make fun of me lol I had a $900 or less budget...

Processor- AMD Phenom II X4 965 3.4GHz (Quad Core) 45nm, AM3 6MB Cache

Motherboard- ASUS SABERTOOTH 990FX AM3+, SLI & Cross Fire, SATA3, USB 3.0 "not too shabby"

RAM- 8gb

Graphics card- AMD Radeon HD 6870 1GB PCI Express 16x dual head DVI, HDMI

Hard Drive- 1000.0 GB Seagate Barracuda 7200 RPM SATA3 6GB/s 64m Cache

SSD- 60.0 GB SSD OCZ Vertex Plus Solid State Drive, SATA2 3.0Gb/s, 180MBs

Case- Thermaltake V3 "not a very good case but I had to cut corners"

PSU- Apevia 700W Extra Quiet Power Supply SLI & X-fire ready

Will I be able to run it without overclocking? I only have 3 fans "2 120mm and a CPU fan" so I don't want to burn up my system if possible. I would prefer not having to OC if I could run it on High Instead of Ultra with over 40 FPS at all times, I know the Phenom II sucks compared to the i5 but I got a really good deal on it from a friend who was upgrading so I couldn't pass it up!
