i have been doing a lot of research and settled on a gtx 460 768mb. it suits my needs perfectly. i will pair it with a i7 870. i have just learned that when u use dual monitors, ur gpu wont idle? has heat issues? so i was wondering if this problem is solved by sli? and if so. would it be better to upgrade to say a, i7 950. will have to add an xtra 160$ for 2nd gpu approx 40$ for x58 board, and maybe 40$ extra for ram. so in essence 240$ extra bucks for lower idle temps and an extra couple of years of viability. just wanted some opinions. thx
As both cards have to be plugged into the primary card SLi won't help neither will an i7 or more RAM or an X58 motherboard. The higher idle clocks is simply a result of the GPU having to do more work to run two screens at the same time.
