More people should complain with Asus support. Checking Asus forums, you'll find there's an obvious problem with a PCI-E video addon + 2 used memory slots. In my case, I had 2Gb (1 + 1), mb with bios version 1104, and it worked fine; when I installed a new PCI-E card, the system was very... very sluggish. Now I have uninstalled 1 memory, I'm using only 1Gb of RAM with the PCI-E card, and it's working well.

Again: checking Asus forum, this is a reported problem, and a bios bug... Asus should release a new bios version, but they seem not to bother, as this is a relatively "old' mb...

ok..here's what you gonna do, turn off your computer..open your system unit and reset your memory card then turn it on again.ok?

If still doesn't work..just let me know here..

which display card is best

As you stated you have a intergrated video controller. Before you add a PCIE card you have to disable the intergrated video in your BIOS. Also in your BIOS where its stated you have a plug & play OS it should read NO. This allows your BIOS to assign IROs and memory usage rather than windows.
Befor you do all this uninstall your PCIE cards software & drivers. Shut down, fix the BIOS reboot & install your software. If you still have problems download this program FREE and run it to clean your regestry: http://www.pcperformancetools.com/exe-file/exe-dll-ocx-extension-unknown-file-type-repair.htm?extension=windows%20error%20codes&gclid=CO3E84jBzpACFSBMGgodh2uHXg
