Need some help on GPU

[Wake28]

I currently have a gtx 460 and i'm wanting to upgrade it.I thought about getting another 460 and going sli, but i have had trouble finding a 256 bit 1g 460 that isn't used or refurbished.

So i have narrowed it down to 3 choices(budget of about 230-240).

I have a ud7 990fx with a 6 core AMD black edition.
16 gigs of geil ram.
750w corsair PS.

I will be switching to msi am3+ board and a 8 core amd before to long.

Card number two definitely, good GPU.

Yeah it's practically a no brainer. The GTX570 is the better of those 3. You could also try finding a 560ti 448 core which will provide similar performance to the GTX570 and maybe be cheaper
