Getting a new graphics card but which one? I get to choose between the: MSI GeForce GTX 460 Fermi Cyclone OC 725MHZ 768MB GDDR5 Dual DVI Mini-HDMI DX11 or XFX ATI Radeon HD5830 1 GB DDR5 2DVI/HDMI/DisplayPort PCI-Express Video Card HD583XZAFC I can get both of them at around the same price, so I thought about getting the HD5830 but then I heard some good stuff about the GTX 460's cooling & noise reduction so I don't know which one to get. Help?
