We need to know what resolution your monitor runs at to appropriately recommend a videocard.
If your monitor is only a 1280x1024, for instance, you need no more than 512MB video RAM (GDDR3 or better, that is) to run Crysis on max settings.
However, any higher resolutions and you'll want more video RAM. Also, you're going to need to pay attention to the type of RAM. GDDR2 is weak and you'll need larger amounts to compensate. GDDR4 and GDDR5 are pretty hardcore and you can utilize less and still do well. My videocard has only 256MB, but it's GDDR4 and has clock speeds around 1GHz, so it compensates for its low amounts. Also, I only do 1280x1024 resolution, so it's not too bad. They say that 256MB GDDR4 can outperform 512MB GDDR3, and since most games are designed for GDDR2/GDDR3 RAM, mine does well. =)
My system I'm presently using just barely meets the "recommended" Crysis specs. 2.2GHz AMD Athlon 64 X2 4200+, 2GB RAM, appropriate videocard, etc. I'm upgrading to a 2.6GHz Athlon 64 X2 5000+ though, and the system will have 4GB RAM. Will upgrade the videocard ASAP, though, and retire the one I'm presently using to my wife's system.
