So, i'm planning to purchase another video card soon to go SLI setup. I currently have a eVGA 8800GTS 320mb. Now the thing is to get the SLI effect do I have to keep with the exact same video card? because I saw theres other brands of the same specs such as XFX and BGF. Also does it matter if the new one is 640mb while mine is 320mb?
Thanks
