Hi! I upgraded my Ram!

As you may have figured I recently upgraded my computer somewhat.  I thought I'd post specs here in hope that an expert would be able to tell me the best graphical options to use while playing MxO.  I've probably included unnecessary information and excluded important information so feel free to bother me until you find out what you need to know.

Microsoft Windows XP Home Edition
Version 2002 with Service Pack 2

AMD Athlon 64 Processor 3000+
2.01 GHz, 2.00 GB of RAM
Physical Address Extension

NVIDIA GeForce 6600 LE 256MB
Integrated RAMDAC
Hardware Acceleration: Full

Thanks in advance.

Could also depend on your connection, I've got a pretty hardcore setup but only 1mb broadband. (compared to 8mb which I was on)

A recent diagnostic check said I was getting 6816 Kbps Downstream and 160 Kbps Upstream. 
The limits of my account state Upstream 128 Kbps and Downstream as fast as my line will go. 
Awesome.
