Hd4850, Hd4870, Sli 9800gt

[HADLEY]

Here I have at present a 8800GTS 256 from XFX and I would like to offer me a new graphical config for Christmas.
I want to know, in your opinion, what would be the best , with a budget of no more than around € 200-220, 4850 between a 1GB, a 4870 512 or SLI 9800GT to 512?
And one last little question, is what you believe in being in XP, add 2 or 4GB of ram is really necessary for my config?

my config:

C2D E6750 2.66
2 * 1GB Kingston HyperX PC6400 DC
Asus P5N-E SLI
XFX 8800GTS 256


Thanks

Unless your XP 64-bit or you are limited to 4 GB (or 3).
But for XP 2GB I think that's enough.
4850 price level seems to me the most interesting, and I think it's better for your config as 4870. The 4850 is already very well

what resolution you play? if it is below 22 "took the hd 4850 should be the case, if not 4870 for more comfort. ADVISABLE the sli because I think it is not too coup and that is of interest to the sli that with the last card for the max time Performance

I play in 1680 * 1050 on a 22 "is a HD4850 is just a little under this resolution? Knowing that apart from Crysis I already turn the last game in this resolution with my 8800GTS 256.
