So, I just got some hardware from my bro-in-law and used it to upgrade our old old desktop. Here are the new items: AMD Athlon 64 x2 4800+ on Asus EVGA/Nvidia GeForce 9800 gx2 4 GB of RAM, 2x333 MHz, 2x400 MHz After getting it up and running with Windows 7 64 bit, I tried running 3dMark06 and it scored in the mid 6000s with resolution at 1440x900. I just wanted to get an idea of whether or not this was a normal level of performance for a system like this. I've been out of the PC customizing business for awhile Also, is it a problem to put different speed RAM together like that? It shows up and is stable, but CPU-Z shows that my RAM is running at 133 MHz!!!
