components suitability for 3 monitors

[Colk]

I wish to purchase Matrox triplehead2 go .
Would like comments of my system suitability to give satisfactory results.
Could i expect good frame rates?

I have Intel core 2 duo E8500 3.16 ghz. processor
Gigabyte GTX 260 video card { gv-n26oc}
Dell 2405 fpw monitor {1} ,1900x1200 res.

Anticipate purchasing 2 extra 24 inch monitors,
not necessarily from Dell.

Many thanks for advice , Colk
