I just upgraded from a GeFORCE 2 to a MX GeFORCE 4 64MB and was hoping for an improvement but have failed to see much of one. I know it was not much of an upgrade but the price was right. What is the big difference anyhow? The main reason I bought it was to correct the jerkiness in Medal of Honor Spearhead and Battlefield 1942. Both of these games I suspect use the same engine and are by EA. Are these games extremely taxing for any system or is ther something I can do. I have an Athelon XP1800 and 512 DDR. Everything such as antivirus is shut off but still the game still jerks around durring the intense battles. All help apreciated.
