Hi! So i'm pretty new to this "building your own computer" scene, as i have only built one out of old hardware and installed a new video card and a powersupply. But here's my question; For upgrading my computer i'm getting the following; An Asus Sabertooth Z77 Motherboard (socket-1155) 750W PSU And a new graphics card. Now i'm torn on wether or not i should get a new GPU, (i.e the Gtx 680 or similiar) or get another one of my "Evga GTX 560 Ti 2048mb physX CUDA" cards and run them in SLI. TL;DR 2x EVGA GTX 560 Ti 2048mb physX CUDA vs A new card similiar to the gtx 680 PS: Here's my system specifics when upgraded; Intel Core i7 860 (Quad core 2.8Ghx 8mb cache) 8MB DDR3 RAM (Speed: PC3-10600 MB/sec) Sabertooth z77 Socket 1155 motherboard 750W Power supply "Video card"
Well, first I'm curious as to the exact PSU you have as not all are created equal. Either way you go will most certainly add more draw on the PSU, and if it's not up to snuff, bad things will happen. Secondly, before grabbing a newer or second card, see how what you have handles your preferred resolution. If the resolution isn't high enough, your video card resolution will be a waste of money because what you have is more than enough.
