hi guys i currently have a decent system which includes the following: phenom ii 720 @3.1 3gb of patriot 800mhz 4-4-4-12 asus m4a78-e motherboard 600w high efficient psu 500gb western digital hdd and asus cucore 5770
however i wondered if it would be worth getting another 5770 for a little more performance however would i see a noticable gain in games like black ops and bad company 2 or moh, i play at 1440-900, also would a second 5770 is xfire bottleneck on my current system as it is not ddr3.
also i would like to ask is there a huge performance difference between ddr2 dual channel 800mhz to ddr3 dual channel 1333?

If your mobo doesn't support DDR3, you can't use it (your mobo only supports DDR2).
Adding a second 5770 would boost potential GPU performance. What resolution do you typically game at?
"i play at 1440-900" at that resolution there'd probably be little bit of a bottleneck, but nothing major, ever tried unlocking the 4th core?. That'd help too.
You should also consider selling your 5770 and getting a single 6870 or even 6950
I think for that res a 5770 is pretty good. Similar money (to an extra 5770) would get you a PII x4 955 BE and I reckon that would be much more beneficial at your res. (I use a 5770 in the front room for gaming up to 1080p in some titles on my HDTV and it still puts out decent frames)
