2 x GTX 760 in SLI, or GTX 770 + 2 x GTX 650 for single-screen gaming with multiple ancillary screens? (Or go ATI?)

Hi all,

Long time reader / first time poster. My question is partially answered in a LOT of posts, but never exactly, so I'm hoping someone can help me out.

I'm spec'ing a system primarily for coding, video, and graphics work, but will also use it for gaming. I have a Precision T7600 on order with 2x E5-2630s. The RAM, SSDs, and graphics are to be ordered from NewEgg.

My current setup has 7 monitors connected to a Radeon 5770, 5450 and a USB to DVI adapter. Of course I want to keep all 7 on the new setup. For gaming I only use my 2560x1440 primary monitor (with Windows desktop extended across all).

I went with ATI on the old machine because they had better multi-monitor support back then, but now to my understanding NVIDIA should be OK for this config.

For gaming performance, would I be better off with 2 cards in SLI with all 7 monitors between them, or a single higher end card with just the primary monitor connected, plus two additional low-end cards to drive the 6 ancillary monitors?

To be clear, what I'm calling the "primary monitor" will be the only screen used for 3D rendering/gaming, and will also happen to be the Windows desktop main display. The other 6 only have the requirement to display text/2D graphics.

Or, overall will NVIDIA not play nicely with this setup, and if not should I stick with ATI? (The only reason I'm going for NVIDIA is that they seem to have a better price/performance ratio).

Any other thoughts or recommendations are appreciated. I'm looking to spend $500 ($600 tops) on graphics hardware.

Thanks in advance,

Edit: In case anyone was curious, this is before I got the 1440 screen:

It seems that I forgot about 2 extra x16 PCIe slots in the T7600, so my plan is to go with 2x 760s in SLI, and if I take a performance hit from having those cards manage all the extra pixels, I can always add a couple of cheap cards for the ancillary monitors.

(Though I am still curious to know if the extra monitors should theoretically make a difference).
