I'm running 2GB because my cpu's overclocked and I wouldn't be able to run my RAM at the same timings with a stable overclock if I had 4GB. 
 
I run most everything on very-high through config editing and at 1024x768.  Good enough for me.  I don't have another $900 to get a faster vidcard, more AND higher quality ram, AND a faster CPU because I wouldn't be able to overclock.  My entire system is performing pretty good considering what I paid for all the parts before overclocking it.  I was just griping because I KNEW one of the components I bought would be replaced with something WAY better within 3 months.  Just didn't know it would be the vidcard.  Seemed like the 8800GT came right outa nowhere.
