newegg is doing a deal on 22 inch monitors for labor day for 100 each with free shipping and im thinking this is the perfect time to get the eyefinity displays ive wanted, but i have a few questions

im slowly getting into pcs but i cant answer these myself yet so here we go

from a performance stand point i get about 50-60 fps on every game i play on max or high settings(the most graphic heavy so far being deus ex)
and im wondering what kind of fps can i expect with eyefinity?

should i upgrade my power supply or would it still be enough?

should i get 4 more gb of ram since its only another 30 bucks or so?

would it not be worth it unless i buy another 6850 and crossfire them?
 
I have a 6850 and using 3 22" screens. Obviously settings have to be dropped but it's quite fine running most games. Just realise that you won't be playing many on max settings and you'll be pleasantly surprised.
