I've always owned ATI cards in the past but since they can't get drivers that aren't complete crap and I can't install more than 4 gb of ram without the video card drivers crashing I am thinking of going Nvidia. I have a 1080p monitor. Would a 1gb 4870 be better than a GTX260 896gb? Or are there driver fixes to allow more than 4gb of ram? Even the newest drivers crash on my 3870 if I have more than 4gb of system memory. I have my cpu overclocked but get the same result at stock speeds. Thanks for any advice.
