No, this is not possible, MSI is coming with a varient to do this. But currently this is not possible. Merged Post: oh MSI is doing something like this then
well it is possible, but all the cards that had this feature were something like 10 years old... kinda pointless you know... ohh and another way to get mroe vRam is to go SLI. also after reading a bit I think you can upgrae the vram on low end PPC macs. go up form 32mb vRam to a whopping 64mb!!!
a single 7800GT would outperform two in SLi, use less energy and have more technologies while being cheaper than buying two.
Never said it was the best option, just that it was one. And the eVGA 6600GT PCIe is $135 on NewEgg... Good luck finding a 7800GT for $270.
dont ya hate that.. i would just buy new computer from alienware and make it custom 5000 mb plus and extra 5000 mb you can realy make it good lol i have a alx and 2 alienware laptops .. the thing is that alienware is geting worse there s---- keeps breaking.. my alx broke 4 times in 1 month it crashed for no reason but lucky a have a 12 year waranty and stuff my spelling is bad i know .. lol
