HD7870 low performance

post #1 of 3
Thread Starter 
Good day,

Yesterday I bought a MSI 7870 hawk, and when I tried it out I noticed it was a bit on the lower end of the scoreboard. I only managed P5250 in 3dmark11. Performance in games weren't that great either. I upgraded from a crossfire'd HD5770 setup and it's almost identical in speed to the HD7870. PC specs are:

Intel i5 2400
Gigabyte B75-D3H
Patriot Division 2 Viper Xtreme 8GB DDR3 1866 kit
MSI HD7870 HAWK
Cooler Master extreme power plus 550W PSU
500GB seagate

On a side note... the psu is 3 years old, don't know if the card could not be getting enough power from it?

Your PSU is probably holding it back.

I'm also worried that it might be the PSU.. but it managed crossfire'd 5770's just fine, and each card draws 100w, so theoretically the 7870 draws less than the 5770's did together
