I have 4 narrow bezel screens with 1366 x 768 resolution each in 2x2 configuration. They should play huge video 2732 x 1536 px with some interactive infographics. And also i have one small touch screen to control them.

So I am looking for hardware setup that will work well. I suggest:

Core i5 2500 Processor
DDR3 8Gb RAM
Radeon HD 6870 915Mhz PCI-E 2.1 1024Mb 4200Mhz 256 bit Eyefinity video card

What do you think guys? Is it enough?
