hello fellow Tom's hardware members,

I have been a long time lurker first time poster. So Since black friday just happend I went ahead and build myself a new computer since my 6year old AMD Athlon 64 X2 6000+ Windsor 3.0GHz and 8800GT cant keep up anymore :( Rest in peace you have given me lots of joy..
So now that thats over with here is my question (Spec. below) I want to run Crossfire but am not sure if its possible to use different brands from different retailers since the Sapphire I purchased is currently out of stock.
I already bought x1 Sapphire 7870(Core clock - 1050MHz | Memory Cloc 1200MHz (4.8Gbps) |Stream Processors - 1280 Stream Processors) since it came in a bundle and am looking to buy either the
XFX 7870Core clock - 1000MHz | Memory Cloc 1200MHz (4.8Gbps) |Stream Processors - 1280 Stream Processors
HIS IceQ 7870 Core clock - 1000MHz | Memory Cloc 1200MHz (4.8Gbps) |Stream Processors - 1280 Stream Processors
ASUS 7870Core clock - 1000MHz | Memory Cloc 1200MHz (4.8Gbps) |Stream Processors - 1280 Stream Processors

so in conclusion is it possible to use to different brands? If so are these cards worth getting or should I just wait till the Sapphire 7870 comes back on sell.

Thanks in advance!

side note - sorry for the wall of text and bad english(its not my first language)

WOW that was fast thanks getochkn I knew I should have posted on here first and not on TL..
ok awesome, so I take it I can crossfire from two different retailers?
and one more question its more of a thought with both fans pointing down wouldn't the second Card get hotter and will that be a problem?
thanks again and sorry for the mass question galore

I would recommend adding one or two 140mm fans on the side panel. Or you can fit 120mm on the side if you wish instead.
It's a nice case and 2 AMD 7870's in crossfire will make a powerful gaming machine.
Happy gaming:)

ya i was thinking about getting 2 140mm for the side just to get that extra cooling.
