Lol your not going to get Ultra with silky smooth frames with those specs....
Imho you can with those specs, he's not using AA or AF.
I use older drivers 266.58 for my GTS 450 1GB Overclock Edition.
My CPU is a Intel E8400 3.0 ghz and 2GB ram
Win XP Pro 32bit
The only mods I use is ENB against the 2-7 second freezes and an enhanced noise filter from skyrim-nexus.
I think it's very important to run a clean system, I have all useless services disabled and nothing's running in the background that's not absolutely needed.
Also defragging your HDD on regular basis and good settings regarding virtual memory, windows behaviour etc. are very important.
I run Ultra (non 1.2) with AA thrue the Nvidia console and it runs smooth.
I'm amazed sometimes when I look at my friend's pc's about how many stuff they run in the background, then they wonder why their games run so poorly.
Actualy besides the allready mentioned bugs in this game (and that's a lot, like broken quests etc. !!) it runs pretty good (with the ENB patch for XP and Dualcores naturaly
