Hello, I purchased the 30 inch dell monitor 3007 WFC-HC. I was hoping somebody might be able to help with video card issues that i'm having. I just found out today that the likely cause to my lag on STERLING when the market gets active is caused by an inadequate video card for this monitor. I also run 3 other smaller monitors. The cards I'm currently running are: ATI VisionTek Radeon X1550 Total Available Graphics Memory: 1022 MB Dedicated Video Memory: 256 MB System Video Memory: 0 MB Shared System Memory: 766 MB Thanks in advance !!!!!!!!!!!!
