First Build, Budget for GPU around 150$ - 200$

[longrtw]

I have a few questions about my build.

G.SKILL Sniper 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333
HITACHI 750GB 7200 RPM SATA 6.0Gb/s 3.5"
ANTEC Three Hundred Illusion Case
AMD 1055T Thurban 2.8 GHz
SeaSonic x750 Gold modular 12V
MSI 890 FXA GD70

Do I have enough power for xfire 6950? i might overclock my CPU and GPUs too?
If in case I can only get a single card, will my PSU be overkill for my system? :-s?
Also, is there any recommendations about graphic cards or anything about my system are all welcome ~ =)



APPROXIMATE PURCHASE DATE: this month (the closer the better)
BUDGET RANGE: 150$ per card ~ I prefer No rebates ... too much troubles

USAGE FROM MOST TO LEAST IMPORTANT: High End Gaming [High to Ultra setting on MW3, BF3, METRO and other graphic intensive game

CURRENT GPU AND POWER SUPPLY: (e.g., ATI Radeon HD 4850 and Corsair 750TX 750W PSU - without this info, it's really hard to help you)

PREFERRED WEBSITE(S) FOR PARTS: newegg.com, ncix.com, and Amazon

PARTS PREFERENCES: Prefer AMD graphic card because I have a mobo support xfire only.... Nvidia card works too if

OVERCLOCKING: Yes
SLI OR CROSSFIRE: Yes [ well someone could recommend me a good single card then it's cool too =)

MONITOR RESOLUTION:1440x900 17", I would like to get a bigger screen in the near future

Please help me thsi is my first build !!! Thank you

I am thinking about whether or not to get a single card like 6950 2gb or just try to xfire lower cards like 6850? What is the lowest price for these anyone knows? (So i could aim for that price =) )

get an single hd 6850 instead of hd 6850 cf.the hd 6950 2gb price will be around $250.
