The 950 should do very nicely, especially with 4 gb of ram. The other 900 series might not be *quite* as good, but the 900 is still a great series, even at only 930 (my understanding is that the second digit is more important, but fair warning, I'm not an expert). And 2gb of ram is nothing to sneeze at. My 540 is only 1gb.
The integrated graphics cards may work, I often find they're more capable than people give them credit for. Got Fallout 3/NV working pretty damn well on an Intel 5500. But if you want to be *sure*, and if you want to play EU/HOI IV, then I'd make the investment to step up a notch.
