Yes, you can crossfire that 5770 with any other 5770. I bought that PowerColor model myself for my garage PC because it was so darn cheap :p . As for your PSU it depends on what kind of PSU you have. Your only problem is your motherboard.

Because your second PCI-E slot is only 4x you will experience some performance degradation compared to running an 8x/8x setup. Crossfire really doesn't like uneven lanes (like 16x/4x CF). Some games are more affected by others, so it's up to you.

oh heres a link to my PSU

the reason i wanna crossfire them is so that i can play strategy games such as Total War series civilization Red Alert 3 and possible Supreme commander and a few high graphic such as crysis... so in your opinion do i go whit the cheaper color one or do i get another of the one i have... but am concern that the mother board can fit on them am mean there too close right ...

you can play all those games on a single 5770 just fine. just dont expect to run all of them, particularly crysis, with all details at full at 1920x1080 res. even 2 5770's will not run crysis on its highest settings with AA at 1920x1080
