I want to move my brother processor INTEL QX9770 to my media center PC and I want to buy a new graphics card for gaming. will the QX9770 will works good with the GTX 480? the GTX 480 is good graphics card for games?
I'd recommend a HD5850 as its the same length as a ATX motherboard so it will fit in the Themaltake mozart VC4000SNS, it also runs alot cooler and you only need a quality 500W PSU to run it, However its not as fast as a GTX480 but will handle games at 1080P fine.
The GTX470 runs hot, just like the GTX480 so I wouldn't recommend it for a Micro ATX or midi tower case. And the HD5870 is 11 inches long which I think will be to long to fit inside your choosen cases.
