Rossfire HD 3850 512mb Gddr3 VS hd 4770

Hi guys,

my first post i think, but i really like the reviews from this site....

i want to ask the masters if the difference between my hd3850 crossfire 512mb gddr3 is superior or not od the hd4770?

i really want to have less power consumition, not an expert gamer, but i like that games really look good and smooth....

the hd4770 has a really good price....

system is:

phenom 9950be 3.0ghz with noctua u12p
4g ddr2 800mhz
coolermaster 690
sata 320g hard drive
corsair tx650w

i hope that you really help me, because some say is better to stay as i am, others says to go for it....what do you think?

two 3850 should be better in most games than one 4770 and at least in my country if you would sell those two you would have enough cash to buy one 4770 or 4850 which is even cheaper. right now, i wouldnt bother selling them and getting 4770. wait for new dx11 cards and see if they can provide lower power consumption and higher performance.

can someone help me choice a graphic card for my computer to play very well at 1280x1024, that is the max of my monitor.....

my budget will be around 180€ and i have 52A on 12v

but you see, mine is hd3850...the memory is not so fast as that..... anyway, i trying to get a crossfire with only 110€ of hd4850...what do you think about that?
good or not?
