What Will give me the best performance?

Overclocking?
I don't plan on over clocking until when it starts to get less useful without it.

Moniters?
I run two moniters but I usually only use the secondary for text, or a video while I'm playing. (the second moniter is a old LG (1280 x 1024) and my primary is a new Asus (1920 vs 1080)

Res/Specs Preference?
I wish to run game on maximum (or close to) resolution and details. (Such as Metro 2033, LA Noire, Starcraft 2, ect, ect).

Current Computer Specs?
Windows 7 Ultimate 32-bit
Intel Core i5 2500k
8.00GB Ram
ASUSTeK P8Z68-M PRO (Mobo)
VE228 (1920x1080@60Hz)
L1717S (1280x1024@60Hz)
977GB Seagate HD103SJ


So what card will give me the best performance? Or is there no difference really between them?
Thank you all in advance!

6870

if you can afford it go with the 6870 its a much faster card and runs great at stock settings (can oc the core to 1ghz with a little voltage tweak easy)

plus if you get a third monitor down the road you can run all three off of the 6870 and you couldnt do that with the 550ti

6870 is a straight choice. It is faster and oc well.

6870 will be faster, and I know someone that would sell you one, that works perfect' for a killer price. Ahem...

I would choose the 6870, it whomps the GTX 550 Ti. The 6870 directly competes with the GTX 560.
