ZOTAC GEFORCE GTX 560 advice/tips; sli help

[rsl1989]

i decided on my graphics card. ZOTAC GEFORCE GTX 560

http://www.newegg.com/Product/Produc...82E16814500206

now i am new to gaming on pc. i think i am mw3 and bf3 ready.
will this display a good max resolution/ fps???

as far as for sli, once i do decide to sli, do i have to sli with identical graphics card or does it just have to be a geforce gtx 560 with the same clocking???

and those who have or have owned this card, what are your opions on it?,

will this handle overclock from stock core clock: 820mhz / shaderclock: 1640mhz to OC - Core Clock: 950MHz / Shader Clock: 1900MHz ( which are the zotac amp gtx 560ti clocks) ???

you can use different cards from different vendors with different clock speeds. i am running a PNY and Zotac. I have the same Zotac card as you. the pny runs a little slower than the zotac. gpu-z reports that each card is running at its specified settings. the zotac is not being underclocked to match the pny card. have not tried to oc anything to see what that would do.
