Can I upgrade the VRAM on my Intel Core i7 iMac?
I have a late 2010 27" Quad Core Intel i7 iMac with an ATI Radeon HD 4850 video card with 512mb of video RAM (VRAM). I'd like to increase that to either 1GB or 2GB, but not sure it's possible or as easy as I can increase regular RAM. Please advise. Thanks!
iMac, Mac OS X (10.6.8), 27" Quad Core i7
