Crossfire Newbie Needs Help!

Hello to all, I'm new to the forums..
With that being said I have a little problem.

I just bought a Diamond ATI Radeon HD 5970 for a cheap price, and I when I bought it was't sure if I can crossfire it to my XFX Radeon HD 5870.
I read that you can crossfire a 5970 with a 5870 but what about two different brands?

Im a little scared for my power supply also.. But I can give it a try? Here are my specs.

ASUS P6T X58 ATX LGA1366 DDR3 LGA1366 3PCI-E16 PCI-E1 2PCI CrossFire SLI SATA2 GBLAN Motherboard

Corsair Professional HX750W 750W ATX 12V 62A 24PIN ATX Modular Power Supply Active PFC 140MM Fan

OCZ Gold OCZ3G1600LV6GK 6GB DDR3 3X2GB DDR3-1600 PC3-12800 CL 8-8-8-24 Triple Channel Memory Kit



Wil it be too much for my PS?

Thanks for your help.

you can go crossfire with 2,3 or 4 different brand cards

Now I just need to upgrade my PS eh? Or try it first and benchmark?

should work fine.
stock at least.

try it first, do a benchmark or use furmark and prime 95 at the same time, put your hand on the psu, if its hot then you need to upgrade

im not sure but i think it should be enough, there is an online calculator which you can use to measure how much wattage you need...

Should I be worried about the brand? I heard Diamond Multimedia doesn't have great support and all? I just bought this because I had a very good deal and couldn't pass on it.

I'm thinking of eyefinity setup or maybe a bigger screen.. Not sure yet..
Any recommendations? I currently got a 23 inch asus screen.

yes, there are brands which have longer warranty, there are brands that full refund, heres the brands id recommend

1-evga
2-asus
3-gigabyte
4-zotac


keep the screen, if you want to go cheap id recommend using the GTX460 for 1080p,you get playable framerates on most games
its just pure win
