I said that when the first rumors of "1GHz" pre-overclocked HD 5870 cards came about and I have been saying it ever since.

The maturity of a process can sometimes decrease overclocking potential simply due to less leakage in the chips. We all know (and is evidenced by AMD's TWKR CPUs) that higher leakage parts can sometimes overclock higher as long as cooling is sufficient.

We have also seen manufacturers using less voltage than what was originally specified on the reference designs. This of course will limit overclocking as well.

What I can tell you without a shadow of a doubt is that newer HD 5770 cards consume less power than the launch samples I have. It isn't anything extreme -about 3-10W - but there is a difference.

allright, thanks for clearing it up. so downvolting and less 'leakage' could be the 'it' factor. cool. thanks man.

I'm a huge ATi fan but seriously there is no reason to buy this card. Your only getting 2 FPS max and at $180 why not just save a few more dollars and get a GTX 460 as this will take care of all your gaming needs at higher frames and reso's for a long time.

The HD 5770 is a great card but the price needs to drop as it's still too close to the GTX 460.

Funny! This thing costs as much as my 5830 ($180), let alone a GTX 460 (which is even with the 5830 in books).

thats funny, my overclock with the v1 reference is way higher than that. very very sad is what that is.

xfx,
1005mhz core
1445mhz memory and only because software stops me.
i can go farther another way but then it wont clock down into power saving.

Speaking of better deals than this ripoff, the US Newegg store has the HIS 5830 for $170 after you enter the promo code. It ends today though.
