ATI HD 5770x2 or an ATI 6870?

as the title suggests,which one should i go for?
I can get 2 ATI HD 5770's to use in crossfire
OR
a ATI HD 6870 ? Both almost cost the same!

and now also a a Sparkle GTX 470 1.25GB/320bits is in the compotetion!
6870 looks like this:

Or although highly unlikely but if i can increase my budget by 30$,i can get a Galaxy GTX560 2GB too but first and foremost i want to know which setup would give better performance with the setup mentioned in my profile?
Or just tell me which is better overall!
Thank you :)

Dual 5770 will be a tad faster then a single 6870 but if you get a 6870 now,you could get another one later and it would be double the speed.

2HD5770 in Crossfire and overclock Equal a stock HD6870 still a little faster cause when you overclock a HD6870 be much faster

6870 should be superior to the other cards

shouldn't gtx 470 be superior to 6870? In terms of memory and bits,it has more of both and not to mention physx. But i have read on a couple of other sites as well that that might not be the case.

physx is good and more then 256 bit is good but remember more doesn't always mean better they are the same pretty much in performance but if you Benefit from the physx then by all means go for it

you already have a 460 really not much different 470 slightly better
