You need to post up your Mobo spec, Processor and present memory mate
Like asking for an engine when we dont know what its going into!
The least troublesome cards and drivers at the mid/higher end seem to be Radeon. But its a waste of time bragging about your high spec card when its in a 5 year old Jetway MOBO with 256 of PC100 memory. lol
If you use a GeForce .. and you dont want problems ,, stick to the Windows Certified drivers, too. Same goes for ATI, but their drivers seem to be better engineered anyways.
For the record, I am using an ATI 9600 Pro and in my Speed box .. an ATI Radeon X800XT Platinum (one of the best cards money can buy)
