A few months ago I got a computer for school/media and some gaming on the side. It was an HP pavilion p7-1298cb or whatever. It had 12 GB of ram, a AMD A10-5700 quad core processor with integrated Radeon 7660D graphics. It wasn't running games very well at first so I assumed the problem was the integrated graphics so I bought http://www.newegg.com/Product/Product.aspx?Item=N82E16814127684 this graphics card for my computer. I installed it and updated the drivers but games like Sleeping Dogs still just as slow as before. WHY?

The problem with that is I don't think my computer has the power supply for it to work. What graphics cards can I get that would be low on necessary power supply but would still be an improvement.

the 7770 only needs about 375w of power although 450w is better

In addition don't look too closely at the on board RAM of the GPU, I noticed in your link it has 4Gb. What is the point with a card that has weak performance. Depending on your budget look for cards with 1Gb on board RAM or maybe 2GB tops.
 
He stated is desktop model number which has a 300w psu. So I would only suggest at most a 7750. It's more than twice the performance of the 630 and uses less power. There is no reason to get more than 1gb at this low end. More will not make any difference in performance and will probably be less performance because they will use slower ddr3.

hd 7770 needs 1x6-pin power connector and there is no way your 300W PSU will have one. So your best bet is to return this card if possbile and buy hd7750. It's great card for gaming on medium details+ it may (i'm not sure, you need to check/post new thread about this) crossfire with your APU.

You can't do dual graphics with a 6770, they highest it goes is 6670. I would also recommend a 7750, just make sure it uses DDR5 and not DDR3, there's a big difference in performance between the two.

No dual graphics with the 7750 either only a few 6k series cards.
 
It doesn't have to be a 6k series since the 7670 and below are rebranded 6k series. 6670/7670 is the highest you can dual. But I suggested the 7750 over the 6670 because sleeping dogs is one of those games where you get less performance from dual. Dual is a good idea when it works but it doesn't work on all games.
 



that's what I meant. 6670.

no matter what it doesn't seem the OP has the funds to do it right so I would suggest lowering the resolution and turn back some game settings and live with what you got.
