Im planning on building a pc later this year. Originally i was thinking about 1 680 4gb for 1 monitor. However, i have now decided i would like a second monitor for video, web browsing etc. I don't want to take power from the 680, so i am planning on buying a cheap GPU for the second monitor. However, i would also like the card to run physx. So, my question is, can a 2nd GPU run monitor 2, whilst doing physx for games on monitor 1. Also any recommendations for cards under £150 to do this would be appreciated
I will probably just get a cheap GPU for a second monitor and let the 680 handle physx (most games don't have it anyway, so a dedicated card for it is probably pointless). However if in future the 680 is struggling, i can just offload the physx to the cheap card, and turn off the second monitor whilst gaming, which will be a nice backup, and give reasonable performance boosts for future demanding titles and possibly a bit of 3-d gaming.
