Question: 5750/5750 xfr or 5770/5750

Hi all, just a quick Q,

I tried searching for similar threads (if one exists please link) but I didn't find anything.

Just wondering if its worth the extra $30 or so to xfire a 5750 with 5770 or just two 5750's. I already have the 5750. Also, I am relatively new to building and just build my first system which runs awesome, so I also want to ask, should I stick with the same manufacturer when xfiring?

I am on a tight budget, so the extra $30 for a 5770 would be worth it to me if I am going to see noticeable improvement over two 5750's.

Thanks for any help

Additional info: Right now I really only play Crysis and Aion.

You can easily crossfire a 5770 with a 5750, however I'd overclock the 5750 some to help compensate.

Thanks, I guess oc'ing a GPU is my next project.

It's quite easy. If you have CCC (Catalyst Control Center), and advanced is on, unlock ATI OVERDRIVE using the little key-thing. Increase the core/mem by 30each, then play a game for a day (leave it sit for a day). If nothing bad happens, raise each by 5mhz. Play another day. Nothing bad? Play another day and raise each by 5mhz. Something go wrong? BSOD? Take the clocks down to where it was stable and be happy.
