Yes I am asking because I really wish it would come out 5790 A 5770 with a 256bit mem interface do you think or is this a pipe dream

If someone knows something about it im looking to sell a 5770 ;) 

More about : 5790

Your thinking of the 5830. That's a 256bit 5770. Maybe now that the GTX460 is out at ~$200 the 5830 will take its rightful place at $150ish.

5830 is a gutted 5850

5770 is exactly half of a 5870

just a mem interface bump I have a feeling would put it right around the same league as 5830 with less juice and heat

just hoping

doesnt really work that way.

tbh, the memory bus isn't that much of an issue. i've jsut bought a 5770 for my HTPC and can overclock the memory beyond 1500 (yeah, 1500). performance jumps, but after 1400 the performance gains dwindle.

it really comes down to performance/price. if the 5770 isn't quite good enough for you then a gtx460 would be a great step up. theres no need to make brand affiliations.

but as 4745 said, a 5830 would be the step up from the 5770 you are looking for, though some would question its value.

The 5830 has more in common with the 5870 then the 5850. It has many of the same specs as the 5770 except for bus width and shaders however so its more like that then the 5850.

Thanks for the graph ovrclkr.

As some/many already know, the 5830 uses the same PCB as the 5870. Thats why the maximum power draw is nearly the same. They cut it down so much to match the 5770 however that they share the same number of ROPs. This really hurts the performance. As does the slower clocked memory. If the 5830 had the same specs but 24 ROPs and the same 850MHz core clock speed it would have been quite a bit faster.

yeah I have a good overclock and honestly I am really partial to the High def Audio
with ATI ...I was pumped when I got my 5770 but now its just lacking when I switched to DX 10/11 1080P is just too much for the card and frankly I dont feel the 460/5830 will cut the mustard for a worthwhile upgrade. concidering price/performance

You could crossfire another 5770, that'd give you 5870 level performance.

The CPU might be a part of your problem. Depending on which CPU you have 2x 2.2GHz isn't very much. Try OCing your CPU to as close to 3GHz as you can get and see what your scores are then.

Not going to lie however, the 5770 isn't a good choice for 1080. 5830/GTX460 at least, the 5850/GTX470 is what you want.

Does the 5770 provide better frame rates when your OCed to 4GHz? If you want 1080, you'll have to get another 5770, or buy a better card.

went from amd 2.2 dual core
to intel dual core and yes at 4.0 and max GPU overclock 960core 13xx mem
they jump bigtime now with the announcement of 6xxx series I may get what I want
