I do have two slots, and was considering the 6670, but was under the impression it would require a psu upgrade.
I'm not sure why I thought that, but the confimation is nice.
While the 7850 is a bit out of my price range, the 7770 isn't terribly expensive..
Do you think it would make a substantial enough difference over the 6670 to be worth the cost?
and, All of these cards could run "comfortably" on this psu, right?
As opposed to, say, barely meeting the minimum requirements when the psu is at full capacity..
On a slight tangent;
Why do video cards always recommend such greater wattages than actually necessary?
I realize that companies build somewhat of a buffer into their recommendation, just to insure that nothing goes wrong, and that if it does, they can't be blamed, but still.. it seems pretty extreme sometimes..
the 7850, for instance, recommends 500-600w minimum.. and you're telling me it would be fine on a 350w max psu..
That just seems silly to me..
Anyways, thanks for the feedback.
I'll look into the 6670/7770 further.
they can all run comfortably except the 7850 which wouldn't have a ton of head room.
Not all PSUs are equal. There are some very bad 500W PSUs that will give less 12v power than your 350W. That's why they have to recommend such a high PSU. Also, they have no idea if you are running a huge hdd raid array, 10 case fans and wtvr else.
One thing i should have asked is your complete system specs. List them and i'll confirm.
The 7770 is a huge step up from the 6670. If you can afford it, I'd recommend it.
Here's how to calculate if the PSU is strong enough:
TDP of GPU + TDP of CPU = total 12v power.
Check if the 12v rail on the psu is greater than the total 12v power needed. Keep above 20% headroom if you are safety conscious.
That's with decent PSUs anyway. Cheap ones should never be used. Yours is good though.
