2x 27" IPS 2560x1440 displays on 1 GTX 480. SLI necessary?

I currently have two displays plugged into my GTX 480
1. Korean 27" 1440p IPS display
2. 26" 1080p


I am planning on getting rid of the 26" monitor and getting a 2nd 1440p IPS display. Will a single GTX 480 be able to support two of these large / high resolution displays or is it time for me to upgrade to a 2nd GTX 480 in SLI ( + a new power supply of course)?


This is my current set up:

Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I53570K

EVGA 015-P3-1480-RX GeForce GTX 480 (Fermi) 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

ASUS P8Z77-V LK LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply

G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL8D-8GBXM

    In desktop mode (i.e. not playing games) you will be fine. However, for games 2GB of VRAM is recommended. Also, I don't know of any games that supports dual monitors if the intent is to play games on both at the same time.

    Going from 1080p to 1440p will likely mean a 40% drop in frame rates.

    Yeah I generally turn off 1 monitor when I'm gaming anyway so It sounds like it'll work out. Thank you!
