i have a gtx260 with 898 mb of memory on it im ordered another one for SLI configuration , here is the question does going sli increase the memory meaning that after doing the SLI would i have 1796 mb of ram or is it gonna stay the same?
System RAM is different (I'm pretty sure you're aware of this).
Edit: Note that you would have increased ram for increased processing. Higher resolutions can still give issues because each video card is still trying to process a higher resolution image with higher end graphics. If you really want a higher resolution, you should probably grab 1gb per card. However, if you're just looking for increased performance at something like 1680x1050 or 1920x1080, then you should be OK.
