I can't believe you're back, Vasiliyi- my Romaioktonoi friend :)
As for your question: i used to play EB on a low-end computer (~2 GHZ CPU (single core)+ ATI Radeon 128MB + 768MB RAM) pretty good on the lowest video settings, so i presume you'll be able to run the game on high (video) performances with the machine you have: i believe that the only thing that matters in EB requirements is RAM, unless you have some stone-aged video card which can't handle even the vanilla R:TW.
Now, grasp your shield and take up your blade!
