Looking for a Gfx card setup for BF3

[lomez]

Hi all, as the topic says im looking to get either a dual card setup or single card solution and im wondering what is the best way to go, wouldve loved the 7970 but just cant stretch to the price that is being banded about atm.

Anyways my budget is 300ish for the gfx also may need to include a psu since my current one is a 650w and the rest of my compnents are as follows.

Corsair dominator 1600mhz ram - 4gb
Intel i5 720 @ 3.4ghz
Gigabyte p55 ud3 mobo
hd5750's in xfire

also would like to play this at pretty high resolutions and decent settigns high would be great.

Any advice will be greatly appreciated.

corsair and i play at currently on my 26" 1920 x 1200 but i would like to play on a 40" tv sometimes at 2560 x 1600 if possible

is it possible that cpu will bottleneck the card or will it be fine till i upgrade to the i5 2500k (eventually) :-S

so twinfrozr seems to be a popular choice thanks for the help, ill wait a week or so after the launch of the 7970 see if the prices drop as for ram, im a bt of noob and does it have to be same brand and model? or is it okay to bang in any brand model of ram ? think ive read somewhere that it had to be matching from the same batch etc etc maybes not.

like i say im a bit of a novice at this well the technical side of it anyways
