HI! Everyone, I don't know much about graphics card and am thus here.. Recently I installed NFS Underground 2 demo from the DIGIT DVD on my WIN XP Home SP2 with 128MD SDRAM, and NIVIDIA RIVA TNT2 Model 64/Model 64 Pro. But, the game ran with nothing on the screen... The EA logo and game video apppeared with no problem but after that I could only see black and white blotches allo ver the screen.. Even if I clicked in the darkness and somehow managed 2 start the game, nothing but the speedometer is seen.. I recently discussed this in the DIGIR FORUM QnA section and tech geeks asked me 2 upgrade my Graphics card.. Now, which card can run such high quality games better and are cost effective too.. Plz tell me more about some such graphics cads with their approx. prices so that this game r may satisfy his hunger for awesome games.... Do I need 2 upgrade my RAM?
