My PSU has 33A on the 12V
I couldnt find a psu with anything above 18A...
Anyways, got an antec 550Watt Neo HE. It has 18A on all 3 12V. I installed it and tried Company of Heroes and it made no difference.
So I also bought the 1300xt pro, and I can say this without a doubt that Company of heroes ran much much much smoother than with the 7800.
I even turned on AA and the card started running it like the 7800 would, except without AA.
I didnt get ram though.
This is 3dmark grade:
The 1300xt pro was overclocked a little, I tried without oc but 3dmark crashed... 6228 was gpu rating without overclock.
and fastwrites was off.
