I have a HD 5670 on a Dell 280w PSU with no problems
only draws 64w max according to AMD specs
very low powered card
in my research on card I found people running on 250w PSUs
as long as you dont get crazy with HDs,Optical and PCI cards
you will be fine
no disrespect to hcshadow but they are wrong on this one
A new more powerful PSU is always a good upgrade but not needed
well the manufacturer recommends 400w. I had a 500w for a phenom ii x6 processor, this same card, bluray drive, 8gb ram, 5200rpm 2tb hdd and the power was stretched. I upgraded to 750 and its great. For his system he may not have problems now but if he wants to run games on his computer or cpu/gpu extensive programs he will definitely without a doubt need a better gpu. Sure you can use this card but if you want to run a game with max settings with this card you really do need a better psu.
it all depends what your cpu will be used for.
King smp you are correct but it depends what he uses it for.
me personally, I max out the card by running sc2 on max graphics, bf2 on max graphics, and hopefully all future games on max graphics.
do remember with those videos that those were recorded with FRAPS
and that the FPS is higher without is recording
also if you want to OC a HD 5670 higher than 850core/1050mem (highest that
AMD Overdrive allows)
than you have to use ATI Tray Tool to OC it
I have pushed the card as high as 910core/1250 (QDDR 5000) with that
though it was 80F in the room at the time and wasnt completely stable
with a cooler room in the winter (68F) I could probably keep that stable
if not push it harder even
