medium settings.. yes its possible for that card depending on the resolution you are trying to run it on. if you are looking to play it at 1680x1050 or higher, no you wont be able to. also some of the people playing it on medium could have better processors and more memory than you.
are u using vista or xp?
medium to high you wont be able to do. you are probably going to be able to play on medium with a couple less important settings set to low. that card will fare much better on most other games.
at that resolution i suspect you will be able to pull off medium. also stick with xp, or go from 2gbs of memory to 4. those 2gbs of memory will go further in xp and you want your system to be accessing those old and slow hard drives as little as possible. also you might want to give your system a overclock if possible, idk how your cooling setup is going to be.
Air Cooling. Saying my video card only has a very large passive cooling system I will get one of those antec spot cooling fans and I will have a personal fan blowing air at the pc externally. And I will have 3x 120MM Fans One at rear one at side and one at drive bays. With luck I hope to win one of those PCs from TigerDirect (100 PCs in 100 Days) and take 2GB from that and take the SataII 250gb hard drive.
With this I hope to get at least get to 720 core and a 2100 memory and whatever I can get the shaders to on the gfx card.. Probably 3.8GHz on the proccesor
crysis isnt even a good game... its more like a bragging right I would say. I played it and it was just REALLY pretty, more like a benchmarking system I would say
