It's probably a problem with your video card... You need to lower video parameters, such as antialiasing etc.
About memory, 8GB should be enough for only 2 clients... But maybe you are running out of memory with your SSD disk. Oddly enough, I noticed that Win7 was taking like 40GB out of the 80GB of one my SSD disks just for a virtual memory file... I'm running 2x80GB SSD, and no mechanical drives, so 40GB is 25% of my total disk space, ouch.
I forced the setting of this virtual memory file to 0, and everything works fine to me. I have 24GB RAM tho. Since then I never had any single crash or disconnection due to lag or framerate drop, which occured a lot some weeks ago. However, I know that GGG improved the game client performance in the meantime. I can still have some lag when meeting some specific monsters, but it's due to bad programming of animation. There might be some incompatibilty with GeForce cards too, which you have and I have. I read something about that on GGG forums.
