Hello, i have an ASUS CM1740-US-2AE. i haven't been able to find exact numbers on PSU but i think its some where between 300-350, again, im not really sure.

CPU: A8-3820
8GB RAM
MOBO: who knows? i guess ASUS

I was wanting a gpu upgrade. I can currently play Assassins Creed 3 on 1080p with just the integrated alone. its not the best but its definitely playable.

i mentioned the 6670 1gb ddr5 so i could do dual graphics on a budget.
According to the newegg i only need 306 watt psu to have a 7750 and for the 7770 it says i only need a few more watts than a 6670.

Any input is appreciated.

You would be ok going with a oc 7850.

7770 is the best choice. Out of these options it is the best card. I hear something about the 7790 coming out @ $150 that would also be something to look into.

True buy you could pickup a corsair 430 watt psu for like $30 and get the 7770 and not have to upgrade as soon as a 7750

i guess this is how i reply? i couldn't find just a normal reply and "answer" didn't really seem like reply.
this will probably be the computers only and ever upgrade. if its a necessity to put a new psu in to get video card in there i guess i would, something budget friendly.

i like the 430 watt idea but it says it needs 340 watts for 7770 , 306w for 7750. if needed a new psu to run the 7750 i probably just go with 7770. If you know of any nvidia cards that would work that would be cool too.

Also i cant see what the $10 difference is between these two. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2941928&CatId=7387
and the other one http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3445895&CatId=7387

these two for 7770s look like a good price for 7770 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7621671&CatId=7387

other one http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7620170&CatId=7387

also some PSUs i cant really tell the difference between these two except that one is modular cabling but im not sure what that means. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4278581&CatId=1078

other one http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7564401&CatId=1078

the two 7750's seem identical to me...

that 7770 looks good howevwe will run a little warm in overclocking or a warm case
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2042279&CatId=7387
this one would be better and isnt too much more expensive

modular cabling on a PSU allows you to connect only the cables you need, instead of having everything dangling everywhere, so modular is much better

the only difference i could see in the card you picked Tumnas was the core clock was 50MHz faster. you said something about that other card getting warm but wouldn't the one you linked run even hotter? or not? i dont really know?
i like that powercolor i picked because it said DX 11.1 all the others just say 11. is there a good difference in optimization?
i dont think dangling cables would be a problem.
also i noticed the two sapphire cards say 600w minimum the powercolor is 450w which isn't overclocked that i can tell
these cases on these cards also seem like plastic heat coffins

just get the sapphire 7750 and call it a day. sapphire makes the best graphics cards for amd. much better than powercolor. i have had 2 sapphire cards including sapphire 7750 which i currently own. both run cool and quiet without any problems .

they are both the exact same 7770, one is just slightly OCed, the sapphire does not require another 150W of power, i have a 7850 and im running it off a PSU less than 600W, and it is overclocked by 290MHZ, so no 7770 will require a 600W PSU, Sapphire cards have a much better cooler than the powercolor ones, it is made by sapphire, keeps the GPU cooler, as well as runs quieter, and as mohit9206 said, sapphire makes better cards, AMD sends them better chips (usually) than other manufacturers so you should be able to OC it better than the powercolor anyway

EDIT: both are the same DirectX version, it must be a mislabeling, both will perform identically if the OC is removed from the sapphire

ok so im pretty much down to.. will running a 7750 risk my psu since it asks for a total of 306w and all i got is 300w? if its not enough and i have to get a PSU theres the Corsair 430w im sure that would suffice for a 7770 since newegg says it need be 340w i think, but if going to do that i could just get a 500w or 600w for about $15 more and then i could easily run an OC'd card with no worries, or i could i think i could get a 7790.
also is the 7790 a double card? and what kind of wattage would it need. i think my a8-3820 would bottleneck it. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7867678&CatId=7387

all the input everybody has put in has been very helpful so far. Thank You.

ok well according to this http://www.tomshardware.com/reviews/radeon-hd-7790-bonaire-performance,3462-10.html the new 7790 actually pulls less power than a 7770 around 140w but i think i seen earlier in the article TDP is like 85w .. newegg says my current computer pulls 261w which brings the total consumption to around 400w if im doing this right? would 430w be enough power or would spending the extra $15 for a 500w save me some trouble?

EXCELLENT CHOICE!!
reviews for the 7790 have been great thus far, i dont believe it is in stores yet, however it will be soon.
a good 430W, such as the corsair that ashish65 suggested (above) would be a great

get a 7770 as its the fastest of all these 3 gpus.... 2x6670s will still be Last gen so id recommend u stay away from them :),
or u can wait for the 7790 to come out as its a pretty decent performer for a 150 buck card

@mohit9206 getting the 7750 and calling it good sounds great but i cant let myself push the psu to max.

so everyone thinks that the 430w psu is good enough for the Sapphire 7790 OC http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7867678&sku=A271-7792 and if 430w is pushing it, i have no problem getting the 500w for insurance

if 430w works that looks like what i'll be getting, i'll wait another week or two and see if a 2gb version doesn't come out because i would be running some AA in 1080p

everyones input has been very helpful. i dont really know who to pick for best answer since you all had very good answers! Thank you.

I want to to pick cia24 since they mentioned the 7790 first but also jaguar since he mentioned changing PSU first.

but my last final question is what is the fastest card i can use w/o getting bottleneck by the CPU A8-3820 2.5GHz ? Would an OC'd 7850 be ok?

i know i picked the best answer, the 7850 OC was looking really good. But i also wanted to take the PSU and GPU that im putting into this prebuilt pc, out of the pc later on down the road and put them into a custom build. probably around cyber monday.

ive come across this 7870 xt tahiti cut down. looks very good. now i know you said the 7850 oc would not be bottlenecked, i trust you on this but i dont quite exactly understand it, since all I've read is that "i5 and up needed for gaming" do you think i could get a brief explanation why the A8's wouldn't be adequate with its 4 cores. would the 7870xt be bottlenecked by A8-3820 or would a A8-3870K make any differences in gaming? i wouldnt really think so??

Thanks everybody once again.
