I have a asus radeon hd 4350 512mb pci-express graphics card coming to replace my old ati radeon 4650 hd 1gb agp card. I was told it will be faster ad better performance even though it is a half of gig less. I was told this is the case because it is pci-e and I will be running on a system with 6 gb of ram and 64bit. Is this the case. I use maya and the old one worked fine with maya and mudbox 2010 but not 2011.the new one supports blue ray and the old one didn't.
